Anyone can ask for a worry to come off. Nothing here is attached to a name, so nobody can prove who wrote one and nobody is asked to. We read the words instead, and the words decide.
A worry comes off the wall when either of these is true.
Send the link to the worry, or the day it was sized and the worry's own words. That is everything we need. You do not have to say who you are, and it would not change the answer.
Every request is answered in three days or less, with removed or not removed and the part of this page that applied.
How many people ask changes nothing. Ten requests about a worry that stays up leave it up.
A request to erase personal data gets the whole thing deleted rather than taken down: the worry, its card, and any address kept with it. Say so in the message.
The worry leaves the wall, its card is deleted, and its link stops showing it. The day's number does not move, because it already counts worries that never went on the wall. Whoever wrote it keeps their emails and their own delete link.
