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.
