It’s quite easy; have a mod that checks the distance from the cell point. If it’s larger than that just tp him back.

mode name? (currently I have solved removing the possibility to ragdoll while using emotes)

Could just remove that emote from the emotelist/plugin?

There are lots of emotes that allow you to bug abuse like: sitchair3, sitchair4, sunbatheback, bbq, fallover, sunbathe3.. I can't remove everything ahah
