The Regular rank is meant for active posters who often need to post to post-approval-restricted categories and are able to do so while following all the category guidelines.
Use post approval successfully several times to show that you know how to do that, and that should be the biggest hurdle. The rest of the requirements just stop bad actors from getting the rank and shouldn’t be any problem for legitimate forum users that follow the rules.
PS: There is no other benefit to Regular other than the ability to post in a few more categories. It does not mean you are trusted by Roblox, it doesn’t give you any other benefit whatsoever. It’s literally just “congratulations, you’ve showed you can be let off the leash without starting a fire”.
All of your posts seem to be in support categories so there shouldn’t be any reason for you to want Regular. Not sure why you are asking.
