To add an official reference (and forum guidelines -- we don't condone that sort of behavior. Just a preemptive FYI.

Looks like you've got the right idea already from Algol -- feel free to "boost" your friend using RAF as long as they're the ones behind the keys of their account, and you're the one behind the keys of yours. It might help to set up a scheduled "gaming time" that you both can just hang out and do some boosting/leveling -- that way you both can get your leveling done without getting hit by any bansticks.
