locking and still charging is not proper; if you read my previous replies you'll notice they're focused on why the lockout happened
1) locking out for TOS breach very often happens without feedback, as does automatic flagging systems - no feedback on TOS breach is sometimes done when the effort to provide an explanation would expose the systems internals or considered unnecessary effort, think spam, system resource abuse, content
2) can only come up with technical reasons for that, neither serve as justification
3) see point 2
