No, it's because you sound like a crazy person and what you talk about is not really constructive to threads about real things.

That could be, but you should also be aware that many people will have the knee jerk reaction to reject statements like yours as being paranoid and delusional. Assuredly sometimes that is an appropriate response, but the drive to immediately reject narratives like yours is to protect ourselves from the doubt that validating your story would elicit. We do not want to believe those things are happening to those around us (even if we accept that they might be in general), and that is a fact that these organizations take advantage of. I wish you luck either way. Stay calm and suspend belief. We are human, and not only do we not know most things, the most important things we cannot know. You can build a composure that allows for many things to be true and not fully know which and still proceed. Otherwise you might be racked with doubt about who and how things appear and have trouble moving forward from this.

How can you tell the difference between an algorithm and topics genuinely being consistently unpopular, though?

On HN specifically? Yeah.

On actually popular platforms? No.
