Hmm, we don’t slay the entire team for stuff (I don’t think we even have access to that command), so yeah, it would only be the person who had it and dropped it in a stupid spot. If I don’t see the guy doing it myself, someone will usually complain about it — unless the guy spawned with the bomb a bunch of times or he kept picking it up and throwing it somewhere and everyone notices. (btw if someone is complaining about someone, don’t always base your actions on what others say — check for yourself!).
For pretty much everything that doesn’t warrant an immediate ban, I warn and if he continues, slay (and kick or tempban if it gets to that point).
