I've never seen anyone do that in a regular thread, and in any case I'm not even sure that's against the rules.
Yeah, same. I haven't encountered these 'high ranked' members doing this kind of stuff. Reporting to the campaign manager should be the first step. This is definitely shady IMO. They shouldn't get paid if you ask me. OP do you have a list of users who are doing this? If you got pages archived of before and after they edited, that should be definite proof against them.
