Why did you lie?

I posted 3-4 things in the last 2 hours, not 50. That's probably why I haven't been flagged.

If you believe me, I do it by hand, and I do it for things that I genuinely believe can be interesting for the HN community.

And yes, a secondary benefit of my submissions is that they also act as a sort of bookmark, because obviously when I submit something that I deem interesting, it's also good to be able to easily retrieve it later.
