Seriously? It's a sub Reddit, who gives a crap. Make your own Reddit sub if you want one. He doesn't owe anybody anyone, it's not a real job. Reddit is just a forum, since when did people get this serious about it? It's nobody's job to run subs. For the people who complain, get your head out of your ass and get a life. Reddit isn't real.
The hell is this even? A reply to something that happened 5 months ago? And not even one that makes sense. Not only are you late, but you've missed the mark completely and are attempting to argue an entirely different point (Is reddit real? Does it matter?)
It doesn't matter what it is. A website forum, a Discord, a subreddit. The fact is it was a community of thousands, who decided to gather together at the same spot on the net. It took time, hard work (From Mods and contributors), and to throw that all away on the whim of one person is the dick move of a manchild.
Argue against it all you want, you'll only convince me further that you know the Mod in question personally.
