Yes a similar thing happened on voat, but voat died and it wasn't just because of the trolls. It was because the only people who commented commented about reddit, it was basically a reddit based forum, and when people got tired of complaining about reddit they just left. Make sure to use this community as much as possible to grow it and keep it this way. Make it a habit to login daily and replace bad habits with this new habit. And 9/10 your favorite community won't exist here, and I highly encourage you to build it if it doesn't and then promote it. I am doing that for /c/frugal: https://lemmy.world/c/frugal
