Their user numbers are available with a web search. Reddit useage dipped towards end of June but has mostly leveled out.

Quite a few mods left, which has had a larger impact than an equal number of general users leaving would. The niche topic sub I was involved in went from four mods to one half-hearted mod. The quality of posts has dropped. Almost every comment thread contains complaints. Reports are piled up.

Most surprising to me when I peeked at the sub this weekend was the amount of borderline-incel desperation and negativity. The sub is for a hobby that while slightly male majority, we had plenty of women contributing with minimal problems. Not anymore. If I were a woman looking at that sub for the first time, I would probably block it. It is so depressing and angry now, I barely recognize it.
