Teams sometimes reward GitHub contributors with their airdrop. Makes sense, devs should be rewarded. 

As a result there is now a airdrop farmer type who uses ChatGPT to find typos and submits PRs against it. They often get merged because it’s free to merge and no one wants typos but maintainers complain that they are spammy and not worth the context shift and attention it takes to review the PR. They are sometimes appreciated but often considered low value PRs.

Repo admins can use LLM to filter out low quality PRs.
