We're aware that there's a current exploit spreading through deviantART in the form of user journals containing random, inappropriate messages and sometimes a link to the exploit itself. Following the link (and accepting the "Outgoing Link" page) results in similar content being posted to the currently logged in users' journals.
We are actively working on a permanent fix and have already put in temporary measures to prevent any further spreading.
If you have been affected by this, or know someone who has, please let us know by commenting on this journal so things can be fixed.
Thank you for your vigilance!
