How old must an account be before expressing a consistent opinion in order for you to take those opinions in good faith?

it's not the consistent opinion that's the problem, it's the single issue (EU is bad) they are purportedly (i didn't check) focused on.

also, "EU is bad" is suspicious in itself because it can't possibly be that everything about the EU is bad. a good faith opinion will find some good things about the EU and be specific in what they are criticizing.

This is the internet. Good faith needs to be earned, on an increasingly difficult scale now that comments may be AI-generated.
