I tend to stay away from it personally. My experiences have all been gaming related (except once), whether being in a guild in GW2 (recent) or a clan in Conan Exiles or ARK and my experiences have NEVER been positive.
I went into the Discord channels for 1D2 games (who's recently changed his name to something utterly stupid) and Decoherent and while I love their streams the hypocrisy and BS they allow in their discords while preaching against things like politics is so sickening that I won't even watch their streams any longer. Yes it may be their Discords and do whatever you want with your discord but it just further pushes the fact that Discord servers no purpose to me.
I went into a Discord that supposedly was based in science, mostly astronomy related and the amount of easily disproved bunk being tossed around and moderators abusing their positions again only reinforced,,,,,,,
You know what, it boils down to a Discord channel is a microcosm world where petty ass hats who've never accomplished anything in life get to play god occasionally. Serves me no purpose at all.
