I have never used Limewire, but if they had distributed binaries that you should pay for, it is a copyright infringement, even if you could technically compile it yourself. There are applications that do this and it’s compatible with GPL license.
The GPL explicitly allows redistributing without charge, even if you paid for it. If they didn’t want their program redistributed, they shouldn’t have licensed it under the GPL.

AFAIK the GPL does not forbid selling binaries in any way. You have to provide the sources of course.
