Following the patsoc bans after attempted infiltration and further talks of infiltration by wisconcom's "Hoxhaist friends" (which we have yet to see), I think it is clear that prolewiki needs to defend itself from infiltration.
To that end, I would like to add a simple principle: on the basis that every editor must complete an application and answer a few questions before joining, I would like to add that any editor who lied or failed to truthfully answer questions during application may be subject to an instant ban.
This is over all pretty standard for most projects (and indeed is standard for any governmental form you might have to fill in your lifetime), but of course our principles must be discussed by the community before being changed.
This principle would be all-encompassing and not just target specific infiltrators. This means, for example, people that answered that they love Joseph Stalin and hold him in high regard in their application but then edited the Stalin article to criticize him liberally could be banned for this. (It hasn't come up yet, I'm just giving an example).
This way we can protect prolewiki from infiltrators and wreckers down the line if they should happen. My main concern is that if many users join and get approved at once, they could start doing a lot of damage faster than we can revert it. And then, on which grounds would we penalise them if we never found out they were part of a targetted effort against the wiki?
