Edit: Thanks for your kind comments on disabling contributions. I’m aware of the possibility, this is just a meme.
Contributions in open source projects are great, needed and make the world a better place after all. Therefore they should be declined politely, optionally by giving a reason.
I hereby inform you that I will no longer accept contributions to this post /s.
I make my code open source and public so people can use it if they find it useful, not because I expect anyone to contribute.
And there’s a big fucking difference between actively hostile and “I’m not interested in accepting this change”.
