It is really comical to read some of the spam comments that I receive. Everything from being chastised to read my comments more often, to write blogs on topics that would actually be found interesting to others, and appreciative comments that have absolutely nothing to do with the blog post they are supposedly commenting on. The funniest part is that they ALL are coming from the same or very similar sources. All are from someone trying to sell a product or service.
This is exactly why I moderate the comments. I especially do not want the trashy content in my comments for any to ready.
