Heh, I do often wonder if they realize why they want followers. Each to their own I guess, and this IS a great method to getting followers fast. More importantly, these people already spam so it's not like you're promoting something that'll hurt the community.
In fact, come to think of it, maybe getting 2500 empty followers will set them straight :P
maybe if they have their own bot to keep them busy they won't bother me with a F4F. I just checked your blog. I see you just did a post titled "People will believe anything" a few hours ago. This bot got 2500 to believe. :)
Oh yes, for better or for worse that article is featuring heavily into my day XD
