Firstly, push forgot password, change the password and email to something never used. Then contact the deviantart help desk, especially if a password reset doesn't work; usually they'll be able to help, and their team is supposed to be quite good at noticing changes in an account so that they can identify the real owner. I'd contact my friends and ask them to inform everyone that the person in the account isn't me, and ask them to notify any ARPG groups I'm in telling them that I'm hacked and to please ignore any ownership requests, etc. should they be made.
If none of those things work, I'd just start a new account. Granted I do have a 70 month premimum on my main account, so I'd be quite angry, but really it's not a big deal.
Just open dA again and klick on the 'forgot password' button, then get a new one and tell everyone 'I' have insulted that that was not me. (That actually happened after a few weeks when I joined dA xD That guy deleted all my pics lol and I just uploaded them again and he never returned)
And if my account gets deleted I just start a new one and maybe tell ppl what happened. Tho I would be highly upset and probably also be depressed |DD
Try to get the email sent to my password, failing that, try to get the dA staff to help. Also, inform all of my dA friends on Skype that the person in control of my account at the moment is not me. Disregard anything they say, and please make journals informing others of my current predicament.
Failing that? Shrug and start a new account. I have all my artwork saved on my computer, and backed up with triple redundancy. I'll not kowtow to the will of some hacker troll. Just start over with a new Jaeger name and hope they get their comeuppance down the line. Bad things tend to end up happening to bad people more often than to good ones.
... and I'm rather prudent when it comes to things. In my car I have 4 flashlights, tire pressure gauge, folding spade, window hammer (to break windows if I end up in the water), first aid kit, umbrella, jumper cables, spare emergency tire, tire jack... probably some other things I'm forgetting.
*^* Hopefully the password is still set to my e-mail! Change the password back! Or in the case it's not gods why did I set my password to something less than 10 random digits on something I couldn't reset my password on! D: Maybe send in an emergency ticket, lots of sites have high priority ticket requests. I would FIND them, and then have my friend trace them and send them dirty socks in the mail
Sometimes admins are good and will usually restore your account, most hackers won't delete your account they just do their work and leave, the ones that do are the real dicks because you usually have to sart over omg. ALL OF THE DIRTY SOCKS
