I will have to charge you $20 for me to take the time out from other important work to undo the work you originally asked me to do.
I coined the phrase in another thread, but here again we have another example of Blackmail SEO
I also think $20 is too low as many have an hourly rate of $50 and by the time you read an email, write an email, locate and remove the links, verify your page still functions and you didn't accidentally break it. Depending on how efficient you are it could only take 5 minutes or even less using form letters, etc. but I only bill a minimum of one hour for contract labor. :)
Just occurs to me someone could run around using a prepaid VISA debit card and pay to remove a competitors links claiming Google is complaining about them and destroy someone's link campaign for a small fee.
Thanks Google, a new way to game the system :)
