Earlier quoted context omitted.
It's all in aid of some streetsweeper being able to add "contributor to X, Y, Z projects!" to their GitHub résumé. Before LLMs were a thing I also received worthless spelling-incorrection pull requests with the same aim.
Are spelling correction PRs not welcome? I'd never put it on a résumé but if I'm following a README and I see a typo, I'll generally open a quick PR to fix that. (no automated tools, not scanning for typos, just a human reading a README).
I always find it a pity when someone has been clever and it's missed. "Spelling incorrection", get it? It's not a correction. It's the opposite.
