On the occasions when I've detected bought accounts by people who are clueless, I've kicked them from the party - when I'm not leader, I ask the leader to kick them before they make a fatal mistake that gets the rest of the party killed.
There's no excuse for playing a job that you simply do not understand.
The last time it happened to me was with a BLM in Boyahda Tree. We XP'd with this clown for almost an hour. He hit one magic burst, total, off Distortion skillchain... in one hour. And the spell he burst with?
Frost. The rest of the time he was just randomly firing off spells on his magic list. Never once saw him switch elemental staves... even watched him cast Aero II with an Ice Staff. Aspir on Crawlers. Random casts of Sleep in the middle of fights.
The whole time the rest of us in the party are talking in tells and finally decide we'd had enough of him, so we ask him if he bought his account (which he denied and just said he was "rusty" and had to "fix his macros")... yeah, right.
I don't remember what happened next, I think we got a link and he Bio'd it after I dropped a Lullaby on it, so we let it eat him and refused to Raise him afterwards, then kicked him from the party.
Strangely enough, we ended up making better XP per hour without him while we waited for a replacement. Sad but true.
