I had the account unsuspended through an appeal sent from a different email address.
In that post https://www.reddit.com/r/rednote/comments/1v92tkg/banned_from_messaging/ , an xhs employee (whose account has since been deleted) told people to appeal to [email protected]. I appealed and got my account back, using the following form: You state that you did not violate their terms, send your account ID, and send a screenshot of the reason for the account suspension.
My disabled account requires identity verification via passport, but since I do not have one, I have to file an appeal.
Their email response time is less than one week.
