Reasons: 1) You are childish about your themeing. A) You tend to favorite your own shit. B) You do not follow a simple set of rules, telling you to credit authors.
2) You have more then 1 account to do comments and favorites on your other submissions.
3) You never listen.
To me, you just need to leave. I could understand you not posting what is in the screenshot if it was your first submission. But seeing as you have multiple account, and can clearly click on the "submit" button. Maybe you should also learn that it is not all about you, and that there is more to customization then having something popular.
As is, my screenshots/themes are not that popular. But they are awesome in my opinion. Do you see me going around creating false accounts and bitching and crying just so I can get the popular vote? No.
Customization is what make YOU happy. Not what makes the other people happy. Maybe you should take that into consideration when you are unbanned.
