My blog spam problem has decreased since adding a captcha (i.e. “type this fuzzy text”). These two, however, showed up, which probably means they were entered by hand.
The first advises the reader to buy some drugs cheap, and then apologizes!.
The second is a clone of a previously approved comment on my blog, but using URLs to refer to another doubtful site.
Sign that once again, both brainpower and ethics are being wasted on a routine basis.
