Hello,
You don't need permission from a moderator to open an account if your current or previous account(s) have all and fully respected
lichess.org/terms-of-service.
You need explicit moderator permission to open a new account when one or multiple current or previous accounts have been found breaching the tos. In which case you should use
lichess.org/appeal.
The relevant part of the tos that covers multiple accounts is:
> Multiple accounts - Having more than one account is not allowed, barring specific circumstances. For example, titled players are automatically entitled to one “public” account, for play in certain prize events hosted either by Lichess or another tournament organiser, and one “private” account, for casual play online whilst still displaying their titled status. Untitled players can create a second account for similar reasons, with some examples including having a private account to hide opening preparation, playing “blindfold” games, or playing games with any other self-imposed impairment. Creating an excessive number of accounts (typically any more than three) will generally not be allowed, regardless of reasons. Creating and closing multiple accounts will also be treated as contributing to this maximum number. As with all other rules, the specific circumstances where multiple accounts are allowed remain at Lichess’ discretion.
TL:DR:
- Max 3 accounts total, one main and two for specific reasons, for the entirety of your permanency on Lichess.
- Closing one account and opening another counts as two accounts, not one.
- All your accounts must be in good state before you can open another.
- If you have had trouble with moderation in one or more accounts and you open a new one to avoid repercussions in the restricted accounts, that is ban evasion and all your accounts will be closed.
