Hello there
About the nojump your demo says it all , if you watch at the timestamp 1:39 , not to mention that it just shows after u got all the punishments which is not enough
that's why , here is my demo for more proof (sorry it's a bit laggy because of my awful internet and i couldn't use viewdemo since it crashes everytime i try to use it)
Demo : https://filetransfer.io/data-package/DWk8N068#link
and about the gag you claim that has no reason , you made me 100% sure that u never bothered to even take a look at the rules , cause if u read them you will see that the rule 15 says : Arguing with players and admins is not allowed! If you think admins don't work properly or you have any complains against them, go to the forum and report in special topic for that or you can report to any High Staff Member.
What i recommend you do is , when you land on the ground keep 1sec before jumping again
here is a video hope it will help :
Have a wonderful day !
