Sounds like a great opportunity to get the original commenter in on the scam. "Psst. Say you indeed made a typo, and I'll split the spoils with ya!"

It wouldn't truly be The Internet without a little bit of Tough Guy Posturing, I suppose. :)

I've made people do a lot of things for like $100.

I'm sure you'd do that and much more for $10k, lol!

I would love to get paid for my terrible posts
