toi don't. But toi can use the
link link at the bottom of any page to write to the staff to request to have your account deleted.
If toi intend to open a new account, please make sure to contact the staff first BEFORE toi create a seconde account, as multiple accounts from the same IP address can get toi banned (and it is much plus work to get reinstated after a ban).
It sounds, though, like just not using the site anymore would suffice for you. toi don't need to supprimer an account for that.
