I agree with Sannse here.

You can have obvious vandalism that can still exist on RC, if it's just a single edit - having a flag for users saying "hey, this guy did something bad" on RC is a helpful thing, even if you don't need a summary. If there's a bunch of vandalism and they're going to be banned anyway - I'd bot=1 and rollback all most of the time, the ban log should be enough to flag to users that someone got banned, it does depend on the situation.
