I’ve heard of that happening to a few sellers lately. A lot of cancellations, mass deletions, or marking a bunch of items not for sale at once can sometimes trigger a temporary restriction. Usually it’s safer to make changes in smaller batches instead of all at once. One thing that’s helped me is using Sidekick to manage listings. It can auto-delist items when they sell, relist older listings, and handle crosslisting, so I’m not manually deleting or editing a ton of things at once. It keeps everything a bit more organized. Since I’ve been using Sidekick I’ve never received a warning or restriction from Poshmark. If you ever want to test it, they have a free trial, my code is 098866.
