I just deleted the first comment spam to appear on this blog. Since I have no plans on wasting much time on moderating the comments I have decided to change the comments policy in two ways:
1. I have enabled word verification option so posting will require entering CAPTCHA displayed by the blog site. This will raise the bar on ease of commenting but I hope it will be acceptable.
2. I have enabled posting comments by non-members of blogspot. This is intended to balance the raised bar on ease of commenting due to the 1st policy change.
