Many different sites have many different ways of implementation and many people seem to have their most opinionated ones.
No blocking and static content.
If it HAS to have user-generated content, then 1) it’s an app, not a website 2) have it untraceable to me from it to me 3) shove it in a jurisdiction that doesn’t care. Still no blocking.
I’d have a “Mute” button, which stops someone’s posts from being seen, and then a separate “Block” button, which would prevent any interaction.
On my sites, reviews are hidden by default until I approve them. Comments require a login and abusers are banned. Contact forms require an email address and submissions can be denied for various reasons (email domain, keywords, country, IP address etc). Most of these require some sort of (non-captcha) human check as well. On my adult site, anyone with an IP in a banned state gets forwarded to an alternative site. I use the same list as pornhub for this.
Could you provide a link to this list?
This artical has an accurate list:

Looks like Florida may be added soon too.
