When these rules got stricter?

I would be thankful if i would get the exact date of changes to the rules.

Hello

I submitted a game request, Project Zomboid and i got this answer: https://imgur.com/a/oQOOLpp

And the question is what`s the difference between these game and games that can be speedrunned on this site, for example:

https://www.speedrun.com/rust https://www.speedrun.com/timberman https://www.speedrun.com/tetris_web https://www.speedrun.com/flappybird

In my opinion when someone requested these games, they should be rejected with the same reason my submit was.

And if these games are a wrong examples i surely can find some others that will match.
