That's an insane amount of spam. The percentage is irrelevant, look at the real number: we're talking tens of thousands of instances of undue burden on the maintainers of open source packages.

And the number of "nice PRs" is essentially irrelevant here: this is not a zero sum game, a thousand good PRs don't cancel out a project getting flooded with bad PRs.

If your event can't prevent substantial abuse of the community you pretend to do this for, you should stop your event and figure out how to do better.
