I'm not willing to purchase without knowing the name. $50 is a little high for my taste in that account, but it depends on its name.
Jagex can't view this site, and a PM of a name hardly constitutes any evidence at all for a RWT or Account Sharing ban....If you insist on the paranoia, then good luck. There are plenty of skillers with names on Sythe, and I'm prepared to wait as long as I want to.
35 right now?
