So wouldn't it be fair to just add the barriers, and move levitation to the old map version category as well?

Also no offense, but if you change the rules to disqualify runs that were made according to the previous rules, why not ban all runs with fire damage boost, coz it was fixed, on the official server you cant get damaged by fire, there are some other speedruns that also utilize the levitation, although to a smaller boost only to the fence, and then theres slime damageboosting which could also be banned if the map wasnt made with the intention of their possible use. The possibilities are endless, if something is in the game, it's a feature, where is the line drawn between a feature, and an exploit? Imagine if they banned all half life speedruns because later versions capped and fixed the bhopping.

After my most recent submission, the rules for the map (Parkour Paradise2) the rules were updated to ban controlled network worsening- however technically the glitch could still be used on public networks, in busy hours, and pretty much any kind of online activity on the network interferes with the connection (I lagged out on the piston level because my friends came back to our discord call and started talking), therefore I propose to just add a skybox to the parkour paradise maps, preventing those shortcuts(I am aware there used to be a run on Parkour Paradise v2 where the runner leaves the map with the slimejump glitch from the top of the house)
