That answer really clarifies the thread for me. Thanks.
Now I read it as some people treating Pornhub as obviously similar to the gambling sites and others obviously different, basing their different viewpoints on the different foundations, and not stating those foundations because they're obvious.
FWIW I can see how login-required porn sites are similar to gambling sites. I'm open on whether mostly-without-login sites are.
In this case, gambling sites, which perform age (and residency) verification.
