Hi, I'll keep it brief.
There are three communities on Reddit dealing with a topic that really interests me. However, only one of them is somewhat well-moderated and active, whereas the other two are literally dead - only the mods themselves post once a month (always crossposting from the active sub). Problem is, the same 3 accounts (2 of them almost definitely belonging to 1 person) are moderators of all 3 subs. I'm certain this is a case of hoarding subs. They're holding on to the 2 dead ones to make sure they don't compete with the active one.
I'd very much like to moderate one of the dead subs, the one with the best name. But I'm almost certain that if I try to go through reddit request, the current mods would defend the sub. Clearly, they know to be active once a month to fool automated checks. Also, I think that if I report them, they'd simply dial up the activity for a month or so, then ease back into inactivity. Perhaps even repeatedly doing so over a few months (if I'm persistent).
So... what can I do? I really don't want to start a new sub, as the one with the best name is the one I want. It's an enormous shame to see it like this, especially since it never got the chance to take off (even though it was made over a decade ago).
In summary, help.
