Here are some solutions I have found to prevent me from getting kicked from the anticheat. 1. When I block-hit, I often times end up in a state where I am unable to hit anyone and shortly after, am kicked by the anticheat. I have found that the best solution is to simply not block-hit while pvp'ing. If you find that block-hitting is necessary, a solution when you receive the glitch is to immediately enderpearl. Enderpearling removes the glitch. 2. When I pearl into slabs/stairs, sometimes I get glitched into the ground and whenever someone hits me afterwards, my knockback is messed up. I end up teleporting around and glitching into the ground. The only solution I have found for this is relogging. Enderpearling, /jumping, and tp'ing to spawn have not worked for me. Hope this was helpful.
