Report a Trademark Infringement
If you feel the username of a StumbleUpon member is illegally using your registered trademark, you may report a Claim of Trademark Infringement. In your claim, make sure you include the following information:

1) The username of the StumbleUpon account infringing your trademark and the web address for their Profile page.

Please submit your Claim of Trademark Infringement to StumbleUpon Support and make sure you select “Report Abuse - Trademark/Copyright/Other" from the “What are you writing to us about?” menu.
