Currently, comments should not be really of concern to moderators, because a) there are too many of them and without proper tools it's impossible to handle them effectively b) a moderator can't even remove a comment from a community.

Eventually, yes, there will be some detection. We'll be releasing many more tools for moderators, like auto-acceptance of posts of users with good history, muting users (with a warning) for certain periods for community rules violation, banning users from communities, maybe even some shared history about users.

Thanks to you. For reading my post and for commenting. Really many thanks for supporting me. I will support you too.
