What rules must new accounts follow?
There needs to be restrictions on new accounts

What rules must new accounts follow?
No rules except following the tos. Just the restrictions like i mentioned

they need to have 1 month before entering in official tournaments..
this way you get less and less cheaters to that contests because they need to use more and more time to access them.,.and they lost interest
This is a very good idea

However many games you have to play to access rated games and forums and clubs, the same reoccurring trolls and cheaters will happily blitz through a few 1-minute bullet games to be able to come back.
A better solution would be to only allow one account per device. That way, if someone were banned for whatever reason, they'd have to create a support ticket in hopes of coming back. But there are still VPNs...
Basixally, there's nothing much chess.com can do, unfortunately. All you can do is report these users and hope that the staff is competent and bans or mutes the users accordingly.
I don't think that people should be limited to one account per device, since kids might need to use their parents' devices to play chess, and the parents might play chess themselves.
