You can get banned for giving gold to an account they think is selling gold or exploiting currency.
I paid for a PL service that has been good to many of my friends. I was banned for 72hours for engaging in mail with an account banned for currency exploits. They were obviously sending my excess gold to their selling accounts.
So its a risk anyway you cut it.
Only thing I'd bot for is honor
I could set up a glide to grind mobs in the caves of AV if I wanted to..thats what bots do.
Yeah I could probably set one up to look like I was talking to NPC's and buying/selling at vendors, if I could figure out how to make it calm the fuck down for a second.
