Being for sports, I’m guessing a lot of the communities keep to their own teams and sports, but I’ve never seen any trolling or toxicity there (more activity in general would be very welcome actually). I’d recommend sharing some examples and why a complete cutoff is necessary rather than blocking a few users.
I think they added a cloudflare captcha. Saw a recommendation for flaresolver but it sounds like that uses a fair amount of memory so I haven’t tried it personally
