What's to stop a bunch of chinese from invading Hacker News and just posting on it in Chinese?

If it weren't such an insanely difficult language to learn, it might be interesting to be part of Chinese tech discussions.

Users in these kind of platforms usually do welcome English posts according to some experience with Xiaohongshu, but registering an account from outside is challenging.

The alphabet may be hard, but grammar is (supposedly) quite easy, compared to eg. Japanese.

I didn't find Japanese grammar to be hard, reading and writing is much harder, what with the different readings of many kanji. I found French and German grammar much harder to learn.

Why would they choose to do so?

They'd get banned like any other spammers?

It’s not spam
