AOL changed it's terms of service. Have a look at this:
"...by posting Content on an AIM Product, you grant AOL, its parent, affiliates, subsidiaries, assigns, agents and licensees the irrevocable, perpetual, worldwide right to reproduce, display, perform, distribute, adapt and promote this Content in any medium. You waive any right to privacy."
Here's the source (with more information) that I recieved this from.
