Hi @Nadia382,
if you did not yet delist your listings and profile, and still want to do it, you may wish to remove all texts and photos first, save that empty state and then delist. If you do that, your pictures and texts are gone completely.
if you just delist, they can be brought back to live for an unknown time.
Your reviews will stay, but not be visible. They are not only connected to your account, but to the guests’s accounts as well.
If you change your mind in a few months, if you ask customer service to reactivate the old account, the reviews will appear on your profile. If you empty the listing first and then delete it, you have to create new ones, if you wish to relist. If you just delist, staff may be able to reactivate them. (I know a host, who keeps coming and going).
