I got temp banned once trying to unstuck people on an old seige map with many of those sand cylinders. The map is not used anymore
but anyway, many people often would get stuck and kicking is just a waste of time to a point. I just kill the stuck people, they will be free in 5 seconds then while they respawn. It was a lot of fun killing them with the partizani dagger.
sadly i got banned from the server because of it, some admin must not like me doing his job.
in battle servers, i see no reason why you should not be allowed to kick people who are stuck, its just no fun for them.
oh
and also, that reminds me. Once I was trying to kick someone out who was stuck, but the kick hit their head and it actually came up as "headshot" team kill. that was pretty funny
