... until they decided it was a good idea to train all power users to grief new users off the site.

It was always like that.

It's due in part to the number of people that kept posting screenshots of their code in their question, and the number of people that couldn't search to save their life. The noise ratio on incoming questions was always ridiculous, and the number of people who don't know how to ask a technical question is staggering. I do wish they had started to ask a series of questions to people for their first 5 or 10 posts to force them to ask questions in a useful way that was conducive to getting answers. The whole site never got over being hostile to new users.

SO had a number of fundamental issues. If you found a duplicate and flagged it as such, you couldn't explain why you thought it was a dupe in the flag. This meant that "this is a different question but the answer is the same" was just tagged a dupe the same way "this is literally the identical question" was.

I stopped participating entirely after a single event. When I was moderating the moderation, and the site decided to give me a trick question to "test if I was paying attention". Yeah, no. I don't have time for that bullshit. Apparently I'm still a top 1% user, though, and I think I've gained another 8,000 or 9,000 points since I left and stopped answering at anything.

The rise of AI and the death of SO is a beautiful beautiful thing. That community is the worst, and this opinion seems to be shared universally by anyone who had extensive interaction with it.
