In my case, I dropped one of my projects because there were so many trolls in the community who called my project crap

Honestly, the biggest enemy at times to the community is ourselves. It is sometimes so demotivating at times.

And the biggest trolls are often the ones with the least knowledge about running projects

It's like the wankers at the moment telling developers not to use GitHub or discord or whatever. They're not going to contribute resources or money to the project, but they'll be a backseat driver
