That was what persuaded me to delete as well. I was supporting the mods in /r/gis and mentioned that they should strike longer, and some user called me "fucking stupid," and mentioned some bs about how the subreddit is important because people find answers there via google.
So I edited every single one of my 11 years of comments to some text pointing people to Lemmy, and nuked my account. Haven't missed it since.
I sincerely hope that toxicity doesn't find its way here.
