This was exposed about last week on the RS official forums.
This clan of 70 people out of no where reached over 2.8 billion total xp and showed up on the recently ranked clans. Funny thing is, all of the clan members were goldfarmers.
Since the community is against goldfarming, I decided to let you guys be aware of it.
As for the owner of all these accounts, your time will come soon.
Clan name (No kidding, its the real name): sflovej
