Microsoft does seem to make it very easy to sign up for their accounts. I used to run a compute service that had a credit card -less free trial. It was peak crypto, so there were a lot of people creating outlook.com accounts, using that to create a Github account, and then logging into our service as a brand new user that way. They would then mine crypto for the duration of the free trial and then rinse and repeat. I think at the time I went through Github's sign-up flow, and you didn't have to even verify your email address to be able to OAuth with your Github account. (I didn't try signing up for an outlook.com email address, so I'm not sure what that entails.) GMail, comparatively, appeared to be more paranoid. We eventually prevented outlook.com addresses from getting a free trial without talking to a human first, and the people looking for a free crypto-miner didn't come back. (They tried Proton as their second choice.) We never banned GMail, so I can only assume that people had a harder time signing up, which is pretty impressive on Google's part.
