So are the MOONs still I thing?

I just sold mine I earned years ago as it seems there's no up to date information about whether they're still distributed or have any utility.

It took several hours of faffing around on the Arbitrum network using bridging and multiple different android apps but I got there in the end.

My question is are they still a thing? Do I earn them for commenting, or if not how do I earn them? Where do they go? What do they buy? My vault with the moons used to be on reddit but now it's not for some reason, why is that?
