Putting "false"
in a YAML file gives you a string, and just false
on its own gives you a boolean, unless you tell the YAML library that it’s a string. Part of the point of YAML is that you don’t have to specify lots of stuff that’s redundant except when it would otherwise be ambiguous, and people misinterpret that as never having to specify anything ever.
Many of the inactive accounts will be people who signed up and started, but made no or too little money, so abandoned the idea. They’re still worth counting when working out how likely a new person will be to make money. Other inactive accounts will be bots or catfish where there was never any intention to make money the way people expect the site to be used, so you can still discount a lot of them, but it’s not all of them.
