GitHub gradually removes these users as they catch up to them, so not helpful to have extra steps. I have a couple of repos which were briefly popular, so when a new user stars it today, and I see 1000s of other stars, it's suspicious and I get a peek into their world.
There are obvious numeric usernames, but also fake orgs with repos for the users to fork and interact with, and a few account takeovers (i.e. someone had signed up for GitHub in 2015 to make a free wedding website, abandoned it, and the account fell into spammer hands). These used to be easier to report.

With collaterals too I presume [1]. I guess I've been the victim of some automated system. They have banned my account without warning or explanation and they've been ignoring my support tickets for about 2 months!

Which is especially ridiculous if this was due to a false positive spam detection as real spammers will not bother with chasing support when new accounts can be created easily.
