Last week we enabled PRs on our read-only GH #ASF #SpamAssassin repo so that people who are most comfortable using git rather than svn can easily contribute.
Today we got the first garbage PR, apparently created by some LLM. It includes deleting everything.
It will not be merged.
But if you are NOT a LLM and want to help with SA, you can now use Github to submit PRs. HOWEVER, I suggest that those doing so provide comprehensible explanations of your intended contributions.
