I was reading this issue from LibreWolf project when I read that some of new GitLab users were asking to give credit card information.
I had no idea this was a thing. According to the forum it’s a measure to avoid bots to use free CI workers time to mine shitcoins.
I know a few people working on similar products and crypto mining as absolutely a big problem. Yes CPUs aren’t that useful for mining generally but that only applies if you are paying for the costs.
