I noticed a few days ago that a lot of items simply disappeared from eBay search like there is nothing or just 1-2 items for sale. I know there should be at least 30-50 from different sellers but only few shown. The same happened with the other items that I am sure there should be plenty of listings for. Tried searching them in a few days later and all went back to normal but disappeared in a couple of days ago again.

No wonder sellers have no sales when their items regularly ON and OFF with showing on eBay.
