> I test my fluency by attempting to pass off as a native speaker on the internet. If anyone ever suspected I'm not a native speaker, they never told me.

How does this work exactly? Do you explicitly say you're a native speaker and then wait until someone realizes you are not and tell you?

Because I don't see it happening that people will tell you they don't think you're a native speaker organically, in a conversation that's going on about something else.

On anonymous and pseudonymous communities, people tend to assume everyone's american for various reasons. This is also true here on HN.

In my experience, when people think someone else is a foreigner, they ask them where they're from. The assumption that they were talking to an american was violated so they try to determine who they're actually talking to. So if I can manage to not violate that assumption, it must mean that my speech resembles that of an american native speaker.
