Steam only shares "Steampowered.com QTY 1"
Itch shares every game or bundle name with Paypal, like this: "Purchase Candied Oblivion by TheSugarRay QTY 1"
MC/Visa/AmEx would only see "paypal#itchio [number]" or something similar...
(Patreon's toads "security and safety team" are known to canvas creators' Discords, etc., to actively search for non-compliant content (even on 3rd party sites) and block creators accounts.)
