I mean whether or not there are exists more powerful users which have ability to check, for example, some IP statistics, to list user-ids that have same e-mail address, and based on that information place someones into some kind of black list.

If such ability exist, do they sometimes perform any repressions to users who are worse than others?

Thank you.

PS. I hope this quiestion will not lead massive downvoting. But I'm not afraid if this will do - it's my only node here :)
