to be extra safe, don't mention paypal by name on your sites or socials, we don't know what kind of terms they're skimming for, best not to create footholds for them to follow to "discover" you're posting shit that they don't like so they can ban you and never tell you why

i HIGHLY suggest you toggle that on
it makes it that much harder for someone to sift through your stuff via google or other search engines, not just for this reason, but any reason
