I'd suggest don't kick if you just see it happen sometimes people do accidentally kill the fellow T by mistake (Lost temple i closed the spike room because an innocent went in but a fellow T followed him but i didn't noticed when i click the button.)
Make sure he didn't spawn in the glitch. on some maps I spawned into the glitch when the round starts (which sucks)
Also a good rule should be:
No RDMing as a detective since if you take out the detective you lose tons of karma
Alright I'll address these things.
Ill add an "intentional" requirement for fellow traitor killing.
Give me example of map where you spawn in the glitch, and we will fix the map.
As for the rdm as detective goes, I'd like to deal with that on a case by case basis. Frankly I don't like the idea of RDM since anyone can define "rdm" however they want to, especially for detectives who have the added pressure of being known innocent. If they make a wrong judgment, they shouldn't get banned for it.
