Why are you spreading misinformation? There's plenty of Chinese gay influencers on RedNote and there have been for years [0], saying LGBTQ talk there is banned is nonsensical.

I’ve seen social media posts by Chinese users on how not to get censored / banned on RedNote, and one common tip is to not share any LGBTQ content. Clearly there’s a fear about it, and gullible young people who flocked to little red book are only understanding reality when they get suddenly banned for something harmless.
