Kleargear.com bills woman $3500 for posting a negative review

A woman paid for items from kleargear.com but never received them, so she wrote a bad review of the site on ripoffreport.com. Three years later she received a $3500 bill from Kleargear, stating that she'd violated the 'non-disparagement clause' to which she agreed when she paid for the items.

Non-Disparagement Clause
In an effort to ensure fair and honest public feedback, and to prevent the publishing of libelous content in any form, your acceptance of this sales contract prohibits you from taking any action that negatively impacts KlearGear.com, its reputation, products, services, management or employees.
Should you violate this clause, as determined by KlearGear.com in its sole discretion, you will be provided a seventy-two (72) hour opportunity to retract the content in question. If the content remains, in whole or in part, you will immediately be billed $3,500.00 USD for legal fees and court costs until such complete costs are determined in litigation. Should these charges remain unpaid for 30 calendar days from the billing date, your unpaid invoice will be forwarded to our third party collection firm and will be reported to consumer credit reporting agencies until paid.
