That's most probably based on member flags, not moderator action.

Note that HN also deprecates stale stories, where "stale" includes "ongoing discussion of some present drama", e.g., bitcoin and NFCs last year, or GPT currently.

dang's discussed this occasionally, see: <https://news.ycombinator.com/item?id=35463948>

HN specifically doesn't moderate posts critical of YC company down, though Reddit's so long out of the gate I'm not sure that still applies. See: <https://news.ycombinator.com/item?id=35463948>

There've been 116 stories mentioning "Reddit" with > 20 votes between 2023-5-13 and 2023-6-14.

I'm doing analysis based on HN front page listings and could update that to see what the actual surviving front-page story count is. It's been ... fairly substantial.

Fewer than 3% of submissions make the front page, and that's exclusive of spammed or moderated content.

Update / Edit:

There've been 16 front-page stories on Reddit since 31 May beginning with "Had a call with Reddit to discuss pricing" (<https://news.ycombinator.com/item?id=36141083>).

As compared with prior years, the 2023 mention rate is well above both the 5- and 10-year history (showing year and HN front-page mentions of "Reddit"):
