they don't even ban the very obvious lalafell rmt invasions on many camps on lindblum...
I think as long as the game is F2P it looks like they don't care at all. Since reports and rmt reports don't affect what is happening so far. There are already many complaints about that. But no reaction...

And i wouldnt call it an exploit either... Remembering the smn-burn parties in ffxi... I don't think anyone got banned from that... only rmt perhaps... and smn burn was by far one of the biggest xp-expoits i can imagine (before abyssea- which wasnt an exploit... it was just game design hehe)
