Yeah, definitely. A bunch of thoroughly dickish moderation persuaded me to never contribute content again. And honestly, I'm done doing free labor for for-profit companies. I'll still edit Wikipedia despite all its issues, as it's all for the public good. But anybody after "hyper growth" can pay me for my labor.

Was this a moderator for a particular tag or one that oversees answers in general? How does it favour vanity metrics over value? Aren't the best answers chosen by the end users?

I'm genuinely curious, I'm not familiar with SO besides having answered a few top questions and getting some points long ago.

A good answer cannot be chosen by an end user if they do not get to see it because Mod-without-a-life deleted it 15 seconds after it was written.

Saying SO is “useful” is vastly understated. The developer world is filled with memes such as “coding is 99% looking up thing on SO”. World’s one of the highest paid profession is powered by SO. They have rigid community rules that everyone likes to complain but it is exactly what has kept quality standards up.
