It’s not suspicious really. They apparently don’t operate in Florida due to those ID laws. It’s more so just that the states have targeted PornHub specifically for their bans to start with and since PH is owned by a conglomerate of sites similar to them, it’s affected many of those sites. Smaller sites remain unaffected often times.

As far as I understand it, the "porn bans" are actually laws that force strict ID requirements, not literally banning porn. (I'm not trying to debate whether they're effectively porn bans, I'd agree they are.) So sites that are paid access only probably have an easier time proving they don't let minors in.
