It even happens on subreddits that aren't as popular. Many years ago I posted frequently on /r/astrophotography, using very crappy equipment[0], but focusing on the processing part, even sharing my own python scripts.
Then one mod decided to actively undermine me, even banned one of my posts, because I didn't use PixInsight (like the rest of "the pros" do). I got my post back up, but that ruined the subreddit for me.
Funny thing, I grew up, graduated CS/software engineering, specialized in image processing and lo-and-behold, my techniques, though rudimentary, were pretty solid.
[0] old binoculars steampunk-ly tied to an old digital camera -- being a teenager with no income meant $0 budget -- but worked better than you'd imagine!
