I logged in after about a week and decided to check on my comments. I had over 70 waiting for me, maybe three-fourths of them supposedly from the same person but all with different starting URLs and email addresses. They were all really nice, full of complements and praise, although also very generic, not always matching my webpage, and clearly written by someone for whom English is a second language. Sadly, my site has apparently been the target of a very polite botnet. I am clearly going to have to add Captcha to my comment fields so that I can differentiate humans from bots trying to praise their way past my defenses.
So if you are an actual human who happened to like my website, said something nice, and then never saw your comment posted, I apologize. You just happened to be overlooked in the flood.
