Comments are, for the most part, very helpful to bloggers and especially to genealogy bloggers. I read an think about every comment. If there is an issue, I try to respond, at least with an acknowledgement that I saw the comment. But recently, we are getting a whole new category of comments, "spam comments." These comments are purposely deceptively complimentary. They usually tell how wonderful the post is and then leave a long or short link or mention of an unrelated business entity. It is getting to the point that if I see anything complimentary that is not very specific about a post, I immediately assume it is spam. I try to delete all of these before they are published, but some are harder to detect than others. Many times the effusive nature of these spam comments does not match the content of the post at all.
My suggestion is that we unitedly, as bloggers, delete all such comments before they are published. We can use any number of systems for reviewing all comments before they are published and making those who comment prove they are human, but what it comes down to is that the comments should not be allowed to go online.
It is my nature, in an event, when someone starts complementing me, I immediately suspect something. This is probably a conditioned reflex from practicing law for nearly 40 years, but it keeps me from getting too carried away with my own importance. As I get effusive and complimentary comments, I always remind myself, being thought important in genealogy is like being the Mayor of Nutrioso, Arizona, a title and not much more (my apologies to the real mayor of Nutrioso, Arizona if there is one).
