The problem I see here is that there aren't any facts about this at all. Just different people tossing stories around. Everything that happens behind the scenes can be speculated. Add in the fact that the only way to justify this ban request is to prove that Smoothrich and Blackzilla intended it from the get-go and it just becomes a huge mess.
Besides, if the mere series of events, regardless of intention, becomes an offense you can be banned for, then the rules should merely be changed to "Joining a Strat faction, warring against it at the same time as another faction and then rejoining it later is against the rules."
