What kinds of web pages should be reported?

If you should encounter a Stumble that is broken or breaches our Terms of Service, please do report it to us, so that we can check it out. Generally, the types of web pages we’d ask you to report fall into one of these groups:

- Web pages that are spammy, deceptive, or illegal

- Web pages that attack your browser or computer

- Web pages hosting malware or viruses

- Poor quality web pages

The following types of web pages are examples of spam, deceptive, or illegal web pages that should be reported if you find them in StumbleUpon’s index:

- Spam (for more information on how to identify spam, read this article)

- Deceptive websites where the address of the web page or links on the page use misleading names with the intent to deceive people into viewing illegal or spam content

- Scam web pages where the page contains misleading information unverified by a third party

- Personal sites with non-topical, personal information belong under “Personal Sites”.

- Web pages that include messages such as “make money now,” “secrets to success,” “guaranteed revenue,” “100% commission,” “#1 best seller,” “get out of debt,” etc.

- Copyrighted material on a web page reproduced without permission

- Web pages where Stumblers are solicited and asked to Like the page

- 404 errors and web pages that take a excessively long time to load

- Frame-breakers (web pages that remove the StumbleBar)

- URL redirects where the initial address that appears in your browser address bar is not the final address you visit

- Web pages that are hard to navigate away from or disable the ability to Dislike them

- Web pages that resize your browser window

- Short URLs for web pages that have been shortened. (i.e. tiny.url,, etc.)

- Duplicate content on a web page that exists somewhere else on the Internet and is not original (i.e. a viral YouTube video embedded on a web page that has already been added with its original YouTube URL or a photo slideshow that “steals” popular photos)

- Web pages with low quality pop ups such as pop-unders, shaky-flashy, or repetitive pop-ups (pop-ups which can be easily closed, and that are not intrusive are acceptable)

- Ad heavy web pages where nothing but ads are above the fold

- Web pages that list nothing but search engine results

- Web pages that require a login to access information or an abrupt call to sign up that is generally intended to get your email address (invitations to join, but which can easily be closed and ignored are OK)

- Low quality web pages in general that have poor, unattractive web design

- Photo URLs where the only content on the web page is the photo, with no way to navigate back to the source




How do I report these web pages?

In most cases, it is enough just to click the “Dislike” button while viewing the Stumble. Our technology will pay attention to the Dislike, and automatically make a note about the quality of the web page.

You can also use the Dislike button drop-down menu to report specifically what made your Stumble poor quality. You can choose to report a web page as:

- Not for me

- Seen Page Already (Duplicate Content)

- Page Does Not Load

- Report as Spam

- Report: Wrong Topic

- Block (no more stumbles from this domain)

When you report a miscategorized page the reporting menu will open a popup where you can report that Stumble as miscategorized, unavailable, or in a different language.

What kinds of web pages are banned from StumbleUpon?

With over 30 million Stumblers, we don’t expect everybody to like the same web pages, but there are some types of web pages which we don’t want in StumbleUpon at all. Our Stumble Quality and Community Support teams do their best to prevent such pages from entering our system. However, if you run into any of these types of pages while you are Stumbling or visiting a user profile, please report them to us:

- Web pages that contain illegal content (i.e. child pornography, online gambling, software/music piracy)

- Web pages that contain malware or viruses

- Phishing or spam web pages

- Hijacked web pages

- Extreme violence or offensive content (i.e. death, torture, animal cruelty)

- Hate speech towards a group or individual

- Web pages that sell or buy StumbleUpon Likes and comments or are built to spam StumbleUpon

- Web pages that are trying to look like StumbleUpon or are using the name without authorization

- Web pages that take control of your browser making it impossible to use your browser or navigate away

- Web pages designed to cause bodily harm to the viewer (i.e. pages designed to induce epileptic seizures)

- Web pages with a lot of duplicate or stolen content from other sources without giving credit to the original content creator
