Its against forum rules to pay people to write comments in your thread, isn't it? The connections I provided between these accounts and Vitor Services should be enough to have all of them banned.
Yes, that's what I know too however banning them is basically any mods call. Not sure what instructions they follow, they must have a set of instructions.
You see, tagging them (neutral or whatever) is really a waste of time because it's not stopping them to bump those services.
Plus, they can just start churning out new accounts no problem. They seem to be using aged newbie accounts, so they likely bought them from somebody in bulk. For example, the accounts currently commenting on Blue Hill Mining:
Name Registration Date

Anyway, whatever we can do to slow them down would be a good thing.
