It sounds like the issue is not necessarily the killbind, but a donor using donor powers to dole out a punishment.
I personally don't really see the issue with a kill bind in murder, though I do see it being more of an annoyance than it would be in TTT.
That being said, donor power should only be used for the most extreme of circumstances. Having someone killbind a lot, to me, is not screaming an emergency.
I feel like a more appropriate use of the donor kick power is to someone who's spamming slurs, using the gun or spammable popcorn to RDM multiple rounds, someone is afk for an entire map, etc.
