Floyd Mayweather Wants Pen Pals While In Jail?

This just doesn't seem like a good idea, from Norm of the LVRJ:
Rapper 50 Cent joined Shantel Jackson, the fiancee of Floyd Mayweather Jr., at her birthday party Wednesday night at N9NE Steakhouse at the Palms.
She appears with 50 Cent in the upcoming film, "Freelancers," which stars Robert De Niro and Forest Whitaker. The rap star is one of the producers of the crime drama, which is due out in September.
Jackson recently tweeted that Mayweather, who has been serving an 87-day sentence in the Clark County Detention Center since June 1, wants pen pals. She said letters should be sent to: ID# 01363917, Clark County Detention Center, 330 S. Casino Center Blvd., Las Vegas NV 89101.

This just seems like this is inviting trouble as many of the people who write Mayweather will try and get something in return, like his money or be part of his entourage.
Also, by the time people write him and he gets the letters, he will be out or close to being released from jail.
