So you don't add any credits so it's skidded and it doesn't even perform correctly. If at least you added credits and told people you were a new developer on this field, I wouldn't be shitting on you.

funkemunky's speed and fly checks ...
No credits, so it's skidded.
bad anticheat for the most part

only really blocks fly by blocking the speed the speed check is bypassed super easily it also falses with elytras etc

Fly is not blocked is a great plugin for 1.13 on my server :) It runs on my Speed server but the player is not kicked! :(
