I google everything so I googled this too, but only got two links to that club. One in English and one in Arabic. And a few links to members of the club. No indication of what it is... Sounds like something someone should look into though.
What's with "Harem Moments for Underage Children"?

Ugh i hope its not what it looks like but ive no idea what else it could be. Hope they get the banhammer.

But who the heck know these days. I think it should be reported so that chess.com can check it out and verify that it is indeed just kids.

Now seems to have been "disabled", which I assume, or at least hope, is "removed" rather than just "rendered invisible but still exists"

Yes, I believe so.
As an SA I've sometimes "disabled" old clubs that haven't had activity in years, and those clubs immediately became inaccessible to me too, with no recourse to reactivate them, they don't show up in my clubs list, etc.
There's an outside chance they might be reactivatable by petition to staff, but that would hardly be fruitful if they were deactivated by staff, and/or were a club obviously in violation of the site's ToS.

It's not really exactly about kids, I know a lot of the Super Admins and there is a very similar club which I would like not to name, but it's basically a group of teenagers and its where swearing is allowed and its like a place for older kids to talk I guess, just don't really care, let them do their thing.

I noticed this club in a user's club list, and it seems the sort of thing that shouldn't be on Chess.com (or, perhaps, anywhere else either). Is there, somehow, an innocent explanation for this?
The club is here: https://www.chess.com/club/harem-moments-for-underage-children
I'd report this privately to Chess.com staff, but the last time I did that with a group, no action was taken (that other group had—well, still has, at the time of writing—notes encouraging terrorist acts and calling for the killing of millions in the US, which I'm fairly sure is a ToS violation too), so that seems a dead end, and also in this case, I acknowledge maybe there's some cultural reference I'm missing?
I kinda don't wanna google "Harem Moments for Underage Children", and realise that simply asking the club admins may not yield an answer that can be counted on.
