So, over the last 6 or so months people have been noticing that deviantART has been getting hit by malicious spammers.
The current trend of these spammers is to favourite an image of yours and then when you reply on their page you get a message along the lines of "I really liked your work. Hey I just got this free X Item and thought I should share it with you." These are all spammers, the links lead to potentially malicious sites. We have been blacklisting these websites and banning all the spammers we can find.
However we need your support in this, we need you to report them too us. We have a section of the help desk dedicated to reports about these accounts, it's titled "Spammer Reports". Tickets in that section are handled within 48 hours during the working week. But unfortunately I've been noticing a tendency that some of these accounts can last for days without being reported. People are aware of them because they're commenting on the profiles stating that they're spammers, but we need these accounts to be reported to us.
If you see a spammer account please file a Spammer Report ticket and encourage others to do so in the future. It only takes one ticket to get an issue solved, but without that one ticket we aren't going to be aware of the issue
