The last time answered a question on Stack Overflow it got rejected.

I was using an unpopular Google API which was returning an unexpected error with a weird code. There was an unanswered SO question about the exact issue from years ago.

I found the answer to the problem in some open source library and added an answer to the SO question with a couple sentences and a link to the source code. My answer was immediately rejected.

There was a way to flag it to ask for review which I did but got no response. I ended up going to meta.stackexchange to ask for an explanation. Finally, after multiple people discussed about it the answer was approved. When I asked why a valid answer was rejected in the first place the response was "links on old questions are often spam and mods just auto-reject".

I won't bother contributing in the future if it takes that much effort to answer. BTW I had something like 20k karma.
