DigitalOcean responded to the complaints that their misguided Hacktoberfest has led to a DDOS of low-quality spam PRs against open source maintainers.
They are not going to cancel the program, and they are not going to switch to an opt-in model. The only change they made is to stop self-promotion of their PR campaign.
They provide their email address at the bottom of the response. I emailed asked them to please reconsider either immediately switching to an opt-in model or cancelling it altogether.
A bunch of technomancers in the fediverse. Keep it fairly clean please. This arcology is for all who wash up upon it's digital shore.
