I don't quite follow.
You have multiple accounts there but three of them are slow. With other accounts it is fine?
In that case one of two things springs to mind
1) If it works with a guest (open in private browsing if you want) but not as an account then the logged in version might display more data and that data makes things slow or might have an error in it.
2) It is a type of shadow ban -- if they ban you then you might just sign up as another, if they make things interminably slow then you might not think you are banned and instead the site is already broken so why bother.
