I agree that it hasn't been on every comment because I found these two, and only these two, that weren't somehow connected to promoting your own stuff:

The other 98% or so of your posts have been promotional in some way. This is far over the line at which we ban accounts on HN.

I'm not going to ban your account right now, but your self-posts shouldn't be even close to 50% of what you're doing here, so please reduce that drastically going forward. In fact it would be best if you'd drop that altogether and simply use HN for intellectual curiosity, which is how it's intended.

From https://news.ycombinator.com/newsguidelines.html: Please don't use HN primarily for promotion. It's ok to post your own stuff part of the time, but the primary use of the site should be for curiosity.
