If you got jailed&muted for crouchbug/slidebug
What is the real crouchbug?
When you crouching and rolling to left/right, you can break the rolling animation to instantly get up. This is crouchbug.
By doing this your hitbox will get crushed for a bit (until your next move, which is either a key press or shooting) and your opponent can't hit your head.
Crouhbug is a glitch which could be enabled on every server and you could easily do it by holding 'c' but in this server, the players voted it to be disabled.
GTA:SA is a 19 year old game and it has a very bad physics based mostly on frames. This means that somehow you will be able to do crouchbug by pressing certain keys, or perform a certain combined task.
By doing this you exactly know that you will get jailed.
What about synchronization?
Sometimes you don't do anything suspicious but your oppoent sees you doing crouchbug or slidebug. This means that your and/or your opponent's bandwith is bad (it's enough if it just a ping spike) or your opponent's fps is very low and we have to calculate the server as well.
If this happens to you, you might get jailed and muted but if you record your own perspective you can post it here and ask for unmute and unjail.
