New Website Lets You 'Blow the Whistle' on Cheating Spouses Credit: lassedesignen/Shutterstock

To tell or not to tell. That is the age-old dilemma faced by anyone with information about a friend's cheating partner. You know it's in their best interest to spill the beans, but you also don't want to be the proverbial messenger caught in the crosshairs.

Luckily, a new online service will let you deliver the message anonymously. Billing itself as an "anonymous infidelity whistleblower," lets you tell a friend that his or her spouse or partner is cheating. For only $24 a month, the online messaging service allows you to receive an anonymous message from family members, friends or colleagues with information on a cheating spouse, boyfriend or girlfriend.

The service is billed as a way to avoid being blindsided — but it seems like if someone is signing up for this service, the state of their relationship is probably already in doubt.  It also calls itself the "worst enemy" of , a website that helps you cheat on your partner anonymously.

If these two websites ever team up, they may have a monopoly on the whole cheating market.
