Dealing with Scum Bus Drives

[dramonic]

I use "your target" and not "name", but then again people playing in my games don't expect normal results that often...

"The person you ended up targetting" would be much worse IMO, even if it's more factual(ish).
Also saying the result should always say "name is whatever" is not punishing the PR for claiming. You're not supposed to have to claim if you're playing correctly for the most part, the fact a redirector can void the powers of a role is perfectly normal and/or balanced in my opinion.
As for a killing role, you'd have to be pretty numb to not notice the person you targetted is alive and another random death has occured when the kill amount is stable (outside of bastard mods) as not being redirection.
