According to Blogger / blogspot http://www.blogger.com/content.g
Our content policies play an important role in maintaining a positive experience for you, the users. Please respect these guidelines. From time to time, we may change our content policies so please check back here. Also, please note that when applying the policies below, we may make exceptions based on artistic, educational, documentary, or scientific considerations or where there are other substantial benefits to the public from not taking action on the content.
Adult Content: We do allow adult content on Blogger, including images or videos that contain nudity or sexual activity. But, please mark your blog as ‘adult’ in your Blogger settings. Otherwise, we may put it behind a ‘mature content’ interstitial.
There are some exceptions to our adult content policy:
- Do not use Blogger as a way to make money on adult content. For example, don’t create blogs where a significant percentage of the content is ads or links to commercial porn sites.
- No incest or bestiality content: We do not allow image, video or text content that depicts or encourages incest or bestiality.
Child safety: We have a zero tolerance policy towards content that exploits children. Some examples of this include:
- Child pornography: We will terminate the accounts of any user we find publishing or distributing child pornography. We will also report that user to law enforcement.
- Pedophilia: We do not allow content that encourages or promotes sexual attraction towards children. For example, do not create blogs with galleries of images of children where the collection of images or text accompanying the images is sexually suggestive.
Hate Speech: We want you to use Blogger to express your opinions, even very controversial ones. But, don’t cross the line by publishing hate speech. By this, we mean content that promotes hate or violence towards groups based on race, ethnicity, religion, disability, gender, age, veteran status, or sexual orientation/gender identity. For example, don’t write a blog saying that members of Race X are criminals or advocating violence against followers of Religion Y.
Crude Content: Don’t post content just to be shocking or graphic. For example, collections of close-up images of gunshot wounds or accident scenes without additional context or commentary would violate this policy.
Violence: Don’t threaten other people on your blog. For example, don’t post death threats against another person or group of people and don’t post content encouraging your readers to take violent action against another person or group of people.
Copyright: It is our policy to respond to clear notices of alleged copyright infringement. More information about our copyright procedures can be found here. Also, please don’t provide links to sites where your readers can obtain unauthorized downloads of other people’s content.
Personal and confidential information: It’s not ok to publish another person’s personal and confidential information. For example, don’t post someone else’s credit card numbers, Social Security numbers, unlisted phone numbers, and driver’s license numbers. Also, please keep in mind that in most cases, information that is already available elsewhere on the Internet or in public records is not considered to be private or confidential under our policies.
Impersonating others: Please don’t mislead or confuse readers by pretending to be someone else or pretending to represent an organization when you don’t. We’re not saying you can’t publish parody or satire – just avoid content that is likely to mislead readers about your true identity.
Illegal activities: Don’t use Blogger to engage in illegal activities or to promote dangerous and illegal activities. For example, don’t author a blog encouraging people to drink and drive. Otherwise, we may delete your content. Also, in serious cases such as those involving the abuse of children, we may report you to the appropriate authorities.
Spam: Spam takes several forms in Blogger, all of which can result in deletion of your account or blog. Some examples include creating blogs designed to drive traffic to your site or to move it up in search listings, posting comments on other people’s blogs just to promote your site or product, and scraping existing content from other sources for the primary purpose of generating revenue or other personal gains.
Malware and viruses: Do not create blogs that transmit viruses, cause pop-ups, attempt to install software without the reader’s consent, or otherwise impact readers with malicious code. This is strictly forbidden on Blogger.
According to Tumblr http://www.tumblr.com/policy/en/content
The intent of this document is to clarify what we consider to be acceptable use of Tumblr.
If you are found to be in violation of any of the below policies, you will receive a notice via email. Unless you explain or correct your behavior within 72 hours, your account will be suspended. [ . . . ]
Redundant Content. Tumblr is not intended to be an all-purpose content aggregator. Users who import or aggregate content in a less-than-meaningful way are likely to be suspended.
Illegal Use. Tumblr may not be used for illegal purposes. Examples of this include using Tumblr for fraudulent purposes or operating a phishing site (used to obtain account and password information).
Spam. Users that do not publish meaningful content, use deceptive means to generate revenue or traffic, or whose primary purpose is affiliate marketing, will be suspended.
Identity Theft and Privacy. Users that misleadingly appropriate the identity of another person are not permitted. Users may not post other people’s personally identifying or confidential information, including but not limited to credit card numbers, Social Security Numbers, and driver’s and other license numbers. You may not post information such as other people’s passwords, usernames, phone numbers, addresses and e-mail addresses unless already publicly accessible on the Web.
Hate Content, Defamation, and Libel. Hate speech and other objectionable content that is unlawful, defamatory, and fraudulent. Note that an allegation of defamatory expression, in and of itself, does not establish defamation. The truth or falsehood of a bit of expression is a key element in establishing defamation, and we are not in a position to make that sort of fact-based judgment. That said, if we have reason to believe that a particular statement is defamatory (a court order, for example), we will remove that statement.
Disruptions and Exploits. We will terminate accounts and block addresses of those who attempt unauthorized use of Tumblr.com.
Copyright. Using copyrighted material does not constitute infringement in all cases. In general, however, users should be careful when using copyrighted content without the permission of those who created it. It is our policy to respond to notices of alleged infringement that comply with the Digital Millennium Copyright Act (“DMCA”).
Mass Registration and Automation. Accounts that are registered automatically or systematically will be removed and access will be permanently suspended.
Sexually Explicit Video. Accounts that use Tumblr’s Video Upload feature to regularly upload and host sexually explicit or pornographic material will be suspended.
