I'm sure you can see that the post linking to the (simplifying) anti-YC blog being accidentally killed by spam filter can raise questions about whether it was really an accident. I'm not saying it was not - I'm just saying the bayesian probability of this being an accident doesn't look that great to me.
Imagine making a scoring system for domains that that takes into account flags and votes on comments that include said domain. Also, your post had a word written in ALL CAPS, arguably two. You can see other comments linking to the same domain at around the same time [1] that aren't marked as spam.
