It seems most of us is getting spams from their friend/watch list to "CLICK HERE" or w/e that takes you to a fake dA page and use your login/pw info to steal your account and then sends spams to others via yours.
DON'T CLICK THE LINK IN COMMENTS LIKE THESE ONES:
"Hey. I think i saw your picture on this website/blog here CLICK HERE"
"Hey. this person wrote something about you in their blog.. CLICK HERE"
"Hey. check out this funny blog!! LOL CLICK HERE"
"hey i thought this iQ quiz was cool. i just took mine!! CLICK HERE"
hey! check this out! I just saw who my Secret VALENTINE WAS !! it really works.. see who your VALENTINE is just CLICK HERE" (newest phishing version).
That is phishing spam invading deviantART. The links lead to a fake deviantART page to steal your dA login details.
Obviously you've already clicked the link in such a phishing comment and have logged into that fake deviantART login page. That means, that your account got hacked. Your account has already sent phishing comments on other deviants' pages with such a link.
GO TO THE OFFICIAL DEVIANTART PAGE (make sure it is the official one by looking at the address bar) AND CHANGE YOUR PASSWORD IMMEDIATELY! Also PLEASE REPORT THESE PHISHING COMMENTS AS SPAM OR HIDE THEM, so that noone else can be tricked into clicking the links!
PLEASE spread the word about this!"
It will always be a weird message anyhow, just don't get so curios about it lol
