They were comments made to me and don't contain any info about the listing or anything a potential bidder needs. Therefore, there's no reason for you to see them.
I don't like the option and the only reason mine aren't hidden too is because you wouldn't be able to see my answer.
Your comment is a perfect example, there's absolutely no reason why anyone else needs to see your question since it in no way pertains to the listing or content. Thanks.
