I've had this site for barely two weeks, and even this short time was enough for comment spammers to catch on. The site emailed me with notifications of new comments, and even from the notification emails, I was pretty certain as to what had happened. Somebody was trying to direct your (and my) attention at the greatness of V!@GRA and to how cheap it was to buy from them. Oh, and they would provide a loan, too, should one be needed. With low, low rates. Personally, I find this pretty sick. What kind of person do you have to be to try and exploit a volunteer's work for your own material benefit? I'm puzzled. Please enlighten me.
As the upshot of all this, anonymous comments, desirable as they may be, are now disabled. Sorry.
