I play as a multiple, yes. I don't have multiple versions of Saede as pod pilots, because its a bit of a pain in the ass to pull that off well, and I really don't multibox enough to warrant that sort of thing.
I roleplay it as follows: Saede has seven clones. One of them is the 'toy' clone that's mostly cybernetic that everyone sees all the time. Two is a 50/50 biological/synthetic clone with as many military grade implants as could be crammed into it. Three is a withered husk of a nervous system that never leaves the pod, and four through seven are basic organic clones with a few utility implants.
All these clones are connected together in real time by a network architecture similar to that used by Sansha's nation to create a gestalt consciousness out of all of the active clones.
Of course, even if the above premise is considered an acceptable one, and I personally don't consider it a steep departure from the lore, there's still the matter of it being highly illegal.
I personally take the opinion that CONCORD are not omnipotent, and banning a player OOC does not act as a proxy for CONCORD being able to reach in the pod and have full control over us, but that's what a lot of the root issues boil down to. We say 'we're in wormhole space, CONCORD can't stop us' and other players go 'yes they can, stop being bads', and that's essentially the root of the entire disagreement.
