Nah. I think ENWorld strikes the right amount of moderation. A little spark is good. When things get uncivil, much less toxic, the mods are quick to step it.
There is no real information about the WatchTabletop to know what if anything they'll to avoid "toxicity."
It is just the nature of the internet. I would say 70% of threads have toxic comments in it, probably 90% if the thread went past a page. Reddit hides them by default, one of its keys to success.
Its always the issue when a forum is mostly the same 100 people sitting in it for 10-20 years.
e.g. this should have been a great thread but soon breaks down.
Battered and bruised, but tried and true. Ain't anyone going to take away my 1e. I love basic/expert, too, but find nothing more satisfying than flipping and turning, now finding and scanning, through those AD&D rulebooks. Arguing about the rules is a feature, not a flaw. So to all you haters...
it takes a special kind of person to stick around to participate.
I do agree the mods on enworld are probably the best compared to the rest of the internet. How they suffer it, I do not know.
I think a new format, where people can just view the news direct, without all the garbage, could be good.
However I think the effort required to get there, is incredibly daunting, to keep it fresh for years and years, in low news cycles. Yikes.
The reason Mastering Dungeons, and the likes of Teos, is so popular, is because the format keeps it all positive. None of the same people polluting every single topic of discussion with their hot takes.
Anyway, I was just passing through, good luck.
