Don't make the mistake of assuming moderator omniscience (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...)! - we don't see most of what gets posted to HN, and we mostly don't read the threads sequentially.
When this comes up, it's usually because someone (yourself in this case) saw X getting moderated and Y not getting moderated, and derived signal from that, when in fact it is nearly always noise.
By deriving signal, I mean bogus conclusions such as "the mods treat X side harder than Y side", or "the mods must secretly be aligned with Y". This is all non sequitur. Overwhelmingly, what you're seeing is randomness (https://en.wikipedia.org/wiki/Clustering_illusion) - but especially easy to overinterpret because of the strong feelings generated by the underlying topic.
There's a well-established process for letting the mods know about posts that might need moderator attention - see https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...
