If you had read my other comments here you would not be asking these questions. A badge that makes sure users feel safer and hackers have to use a real name card on itch and spend money and wait, to successfully spread malware. It does not hurt newcomers by blocking them, but newcomers have to buy into getting the badge; it makes old users more trustworthy as they should be.
Sandboxing is the solution if you think the browser is a solution, and it ain't looking good I tell ya. Java had sandboxing for 30 years nobody used it, outside of applets, except me; not even Minecraft modders. So I'm making my own JVM to fix that since Oracle foolishly removed the sandbox in the latest Java version... in the meantime we have to embrace native (or close to native performance/featured VMs like Java/C#, js can't do efficient memory sharing between threads without copying f.ex.) because of power usage: Linux on ARM is the only viable platform long term and until we get a better sandbox than V8 (even with WASM) that will not work.
Time is trust, you want to remove the breaks to go faster. That's an accident waiting to happen.
