Since I was the multiboxer with my guild, which is part of a cross-platform community kind of thing (started with SWG and covers about 7 MMOs now, with plans for the future) they asked me about loot rules.
They run Suicide Kings, but that makes allowances for mainspec/offspec and you can apply that to main character/alt. That's what they had so far, but what of your drones? Aren't they just alts?
What we came up with was you could do two mainspec rolls no matter how many characters you have. The first roll is for your "main" out of your group of 2, 3, 4, 5, however many. The second roll is split amongst your alts.
This applies for any "Visitor" multiboxers too, like yourself.
It's probably far from the best system, but it's better than that crap these guilds are telling you about "Thanks for coming but you can't roll because you'll steal all the loot"

No way am I spending the repair money to help people who won't let me possibly profit from it. Nor am I going to accept repair money as a "payment for services rendered" because I'm not that kind of multiboxer.
