Pinterest comment not allowed

Pinterest comment not allowed? This is a new one. I sometimes hit the spammer type comment block but I have only seen the warning dialogue box below once. I was pinning on a client’s Pinterest account and saw this message:


The pin was just an inspirational quote with nothing offensive so not sure why it wouldn’t be allowed and the block didn’t say the website was spam. I looked on Pinterest help for clues, but no luck there! Has anyone out there seen this too?
