I got an invite to join last year and signed up to test it out.
Felt like there was a lot less people and a lot less content on it than Mastadon.
Unless the users/content now really starts to take off, there's not enough on there to make it interesting.
Some forums are still reasonably active. I use Whirlpool fairly regularly. Mostly tech related, but has lots of other sections too.

This.
I use Adguard, if a site blocks me for it, then it goes on a black list of "never visit" sites.
In a few cases, if I use and like/support a specific site a lot and that site is ad supported with no other ad-free option, then I white list it.
But to read the odd crappy article? No I'm not disabling my ad blocker.
Agreed, it's so good.
