You can still do tag search to find games that are tagged like adult, hentai and ect.
People just cant use the lazy way anymore until Itch.io can find a payment processor that isnt corroupted by a goverment or Australian Karens. First then they likely will get re-indexed.
The only option people can do to re-index games again, is to remove ALL payment options on their games. Including donations.
(You can still have a patreon or any other supporter site as a way to pay them)
