HN can obviously be gamed, but I think when people ask or share tools they use to solve certain problems, that demonstrates a desire to discover something new showing that there are ways to discover valuable tools without ads. That type of discovery is a lot different from an ad on Instagram for a drop ship company advertising its US roots while repackaging cheap Chinese manufactured products. In the latter example, I feel the ad exists entirely to sell something that is completely unneeded rather than to inform about something the person genuinely could find valuable.
