But there’s also later more detailed guidance:
”One person or legal entity may maintain no more than one free Account (if you choose to control a machine account as well, that's fine, but it can only be used for running a machine).”
Yet this is something I, and many others, do because we don't want to mix business with pleasure. In fact I absolutely refuse to do so because of security reasons.
In practice this is mostly so github has a reason to misuses like bots which might not be caught by the anti-spam measure.
They do mind a bit but not too much, and you can get help from support having literally stated that you have multiple accounts. For instance if you're testing an extension or integration with github, and there are specific interactions between different users… you kinda need different users to test it. And mocking github may not be sufficient.
The work account is strictly to communicate with/provide patches back to upstream projects.
I have multiple personal accounts on Github. One for each employer I have worked at in the past couple of years, and my personal account that is tied to my own identity and is used for my personal time projects/open source work that is not tied to $work.
I'm definitely kidding, but unless there is more in there TOS (which I don't intend to read) I don't see why this wouldn't be a workable loophole
Doesn't remove their need to implement a more reasonable way of scoping tokens, though.
