Ban users across chats #39
Description
Make possible to block someone from posting messages to kotlin_forum (and other chats in family except from kotlin_meta) by marking kotlin_forum post as either:
/ban, /ro 1h/1d/1w/1m/1y/inf
kotlin_meta holds own block list, so people banned/read-only in chat family can write messages to kotlin_meta, until they banned there for spam or rule violation.
