Dmca took my IMVU account away from me, saying that I abused the dmca act but I did no such thing. They said I cant appeal

You need to hire an experienced copyright attorney to represent you. You can't do this yourself.

The Asker and, hopefully, the Asker's attorney will have the process set out in DCMA. Have the attorney determine what the options are.

I agree with my colleague's advice. You should be discussing your best course of action with a lawyer in private and certainly before taking any action on your own. You can start by calling around to several for a free phone consultation, get some insights then pick the best fit to work with. Best regards, Frank Natoli-Lapin, LLC

"DMCA" is not a person. The acronym stands for "Digital Rights Management Act" -- a part of the Copyright Act. A rights owner has apparently complained that you have infringed, at least once [likely more] its copyrights via your conduct on IMVU.com. You and your own copyright attorney need to read IMVU's "Counter-Notification" section of its Terms of Service and decide whether to send one [visit the link below]. Do NOT simply send one yourself because if you have infringed then sending the counter-notice adds to the unlawful conduct for which you can be sued. So speak with your own copyright attorney.
