Non-native English speakers are 100% welcome on Hacker News, and the rest of us are amazed by how good your English usually is.

Automated comments are what people here feel strongly about rejecting. It isn't just the LLM-written ones that trigger such reactions, but also comments that have been filtered through translators/editors/checkers and so on. Readers are becoming hypersensitive to these, so it would be much better to just write in your own voice. The benefit of authenticity outweighs the cost of a few grammar or spelling errors.
