I did read the post. The guideline is specifically about situations like this one. You should not describe your company in relation to YC unless you are actually affiliated with YC. Being rejected is not an affiliation. Neither is being an applicant.

That said, I think there's nothing wrong with this post, but that guideline is there for a reason.

It doesn't say you can't mention YC. It seems like this post only goes so far as to say "I applied but was rejected."
