I never posted in my journal before but I'm utterly confused and I really need help! *whines*

All my art has been deleted by DA staff!! According to the note I got it's because of "art theft". HUH? Art theft? I made every single piece I posted, I still have the psds to proof it.
I wrote 2 messages to the staff asking for an explanation but they are not responding. Even art that has been here for more than a year has suddenly been deleted.

Any one else having the same problems? Is it because I have a free account? I don't make ANY profit of my artwork, I have a few requests for prints but I'm NOT interested in making money. It's just something I do to keep me occupied. *shrug*

Sorry to bother you with this, but to quote a gorgeous platinum blond :"I'm at the end of my bleeding tether!"
