I got banned at easypic recently. I don't cheat and I don't even post every day. I emailed him twice asking why. I was concerned maybe my host had been down etc.. I was a bit puzzled because of my CLEAN record. The only thing that I can remember is his page went white and to dns error once when I submitted. Oh well...
I emailed twiced and asked nicely. NO reply. As far as I am concerned if he can't return my email and tell me why then I probably never even did anything wrong.
I just summed it up to HIS loss and moved on..
IF someone NOT matter how BIG or ELITE they are in this biz don't have enough respect to answer an email, I could care less if I am submitting to their site..
Anyway, don't worry about that Webmaster ! There are plenty of places to submit your site to and webmasters that YOU can get ahold of..
