on my server the players are blatantly buying and selling rss in world chat. i even see dwarf players selling honor for the current event ($x for set of mechs suicided). on pretty much every game i've ever played, this sort of RMT has been against the rules. one of my house members PM'd support who confirmed it was against the rules. otoh, i sent some screenshots of people buying/ selling, and support only made some comment about how 'autoshield prevents this sort of thing' - err, ok).
i think hitting an alt is a little more of a grey area, though i'm not really a fan of it.
