it's a Japanese word for "weird". I'm guessing that OP is a bit of an Otaku (aka "obsessed with Japan") -- which is either ironic or completely appropriate.

I thought it would be weird to replace (b) with something, so I decided to search for characters from other languages.

I thought it was an aposite joke. A, "you're local weirdo, or you, might count in a foreign language".

My first thought was that they were an LLM, but then checking their profile it seems they've been around since 2012 and have a comment expressing that they seem to get accused of being an LLM a lot, and suggesting people don't do that.

Any sufficiently interesting person eventually gets accused of being an AI. Quite soon these accusations will nearly always be accurate.

/headscratching They don't have to be, do they? It is possible that some people will build identity systems with norms that e.g. humans type with their own hands. These could become popular, at least conceivably, in certain areas. Hard to enforce for sure. And getting harder and harder to distinguish reliably.
