What i've seen with my own eyes: Completed my service fine, and left my 100k intact.
What i've heard from clan mates: Proceeded to tell them all about Sythe and what i do, and i keep Sythe and my clan completely separate as they disapprove of RWT. Then he offered my clan free questing/firecapes though he only has 1 vouch for free skilling(from me). i see no proof he knows how to do one, but that doesn't mean he doesn't.. Lastly, i'm told that while i was away he went back on to my account a day after the service was completed and started saying that i was "gay" from it..
