In addition to what the other replies have said, just a couple of years ago some company or group was running a competition which gave away something and caused a bunch of nuisance PRs adding almost literal garbage to READMEs. After criticism the ones running the competition eventually said repository owners could opt-out. This is only from recollection so I might have some things wrong about it. Fortunately it hasn't repeated itself.

This sounds like Hacktoberfest with Digital Ocean, specifically. I could also be wrong, but that is the one that stood out to me.
