Please add something to FFXIV that disables 3rd party software interactions.

And if you're kicked without a reason, you can report them for kicking you.

Not from a PF group. Their group, their rules.

if os.programs.any? { |prg| prg.is_reading_memory? }
return "stop"
end

You clearly know absolutely nothing about computer programming. Final Fantasy 14 runs without administrative privileges, and therefore it can't even query the list of programs that run with administrative privileges, let alone knowing if its memory is being read. And even if it ran with administrative privileges, bots can run using SYSTEM privileges.

Parsers don't even work using memory reading, they read network packets, which FFXIV has no way to detect since it is a passive process.

And even if they managed to solve all of that, you can simply run FFXIV in a sandbox and interact with it from outside. Keep in mind that at this point it would already be acting much like a virus does, violating the european GDPR and also possibly causing virus scanners to (rightfully) detect it as spyware.

If it were a simple problem to solve, it would've been solved a decade ago.
