While Blogger is catching almost all of them, it makes me feel bad. Here these people are spending hours copying and pasting (I assume) comments onto blogs and those comments are being trashed without ever being seen. Not that I want to see them.
Are the people getting paid anyway? Are they basically slave workers?
Are they aware that their spam is being filtered? Are they working on ways to avoid being automatically detected?
The spam comments annoy me, but it makes me wonder about other things.
