While I have never been banned myself, the screenshots I've seen of ban messages generally do indicate a specific reason, such as disrespectful comments, attacking other Scratchers, posting inappropriate projects, etc. and the ban page (image here) gives the last few alerts before the ban, and I know alerts give both a specific reason and the specific project or comment that led to them.joy784 has sent me every message from the scratch team hes got and it shows nothing about what he did wrong, just he did wrong.
clarification is the bestification
