I like it, its simple enough and would not require hard forks or anything of the sort. It could be implement right on to the steemit website, granted if the users are bots this would not do anything. But... I'm inclined to think that most of the accounts that beg for follows are real people, like the one you flagged on this post below.

I'll be waiting to see what some of the bigger users have to say about this. I find it funny how you are thinking of ideas and I'm writing satire about this problem.. but you are being much more helpful than I am.
