I know how you feel. My forum that i sold 3 years ago i had made a deal with the new owner to just make my admin account a normal member account so i can still browse around the site or even post on it if i felt like coming back there. Just earlier this year, i tried to login to my account and i was banned besides all posts removed.
Heck, even all the sticky threads with the rules i created and forum news i posted about changes...etc i made was removed. Basically the owner erased all trace's of me the original owner of the forum. After making attempts to contact the owner, my emails was ignored. Eventually after 2 days i just gave up and will never visit the site again. The 2 admins on there have not even logged into there accounts in a few month's. I thought i put the forum in good hands but i was flat out wrong.
Yes i was really upset but really nothing i could do so i moved on.
