Don't Get Played with PlayerBlock.com
Based on the highly optimistic starting assumption that "people cheat and lie while dating and in relationships," PlayerBlock claims to be the first ever text-based service that enables romance seekers to investigate the dating habits of others (the Web already hosts similar date- and fidelity-tracking sites).
PlayerBlock members (who pay $4.99 per month for up to 100 messages) are encouraged to report both positive and negative dating experiences, with their insights then linked to the phone number of the tattled-on party.
There's a whole host of different features you can access with different codes you send to 25625 --- including RANDOM, or as the site says, the entertainment portion of the service. With this code, you can get random samplings of disses from other clients!
