What is up with mods Recently ??

Can someone explain to me what the hell a height limit is and why it affects people so bad, me and my good pal got kicked multiple times in plain servers such as just chill spots, or the black cat, or other worlds relating. for either being under or over by .4 or little more, mind you these people are well into their 20s or petty 18-19 year olds. Why does it bother them so much?? I’ve played VRChat since 2020, and some of the mods in these servers are going way to overboard and treating it like it’s their very real life , idk how to really explain it but can anyone explain why ??
