Discord is the future in the same way that proboards and .tk domains were the future.
Sadly where a lot of the useful data that might have landed on proboards forums and .tk domains was archived then implosion of discord will probably see a lot of useful data, both generally and historically, lost to the abyss and I don't think people have learned to take incremental backups or something to recreate the service like the demise of geocities.
As far as resetera... I have no fondness for the place (their mindset and whatnot is antithetical to common sense, basic observations of reality and ideas of community building from where I sit) but owing to the loose lipped game devs that pass through it from time to time they have generated some useful advance information, and put things into place after the fact, before.
Never head of m.o.b.a. network but seems like much as the name could imply they run a bunch of game specific interest sites and stats sites https://wearemoba.com/#brands-target
(multiple for league of legends, overwatch, vainglory, actifact the dota card game, dota 2, smite) which if we are talking about rarities in current space year then I would not have placed much money on such things being around still, that said I don't play any of those and have never even heard of vainglory.
Nowhere near interested enough to know if they were self spinups of acquisitions and what the timeframe was there, no who is behind it. https://ir.wearemoba.com/press-releases/en
if you are bored.
Am slightly curious as to the 4 million though. Valuations in general are basically meaningless at this point, however seeing the investor relations thing then they are seemingly concerned with growth, profit and the like. That said umbrella site and built in audience is a pretty decent loss leader or aiming for long term returns.
