Switch to a different client that doesn't spy on you and ruin the network, and actually gives support for their product.
If you like Morpheus, then try out Gnucleus, the software that they ripped their source code from and made worse. If you're looking for a change, then try Bearshare, Limewire, or Shareaza. If you decide to go for Bearshare or Limewire, then don't install any add-ons when it asks you to.
Just remember if you switch clients, you're not missing out on anything, except for a lousy user experience and lots of bugs. They all connect to the same network and return the same files.

Morpheus used to be great when it was on Fasttrack, and it might be good again when they finally come out with their long-awaited 2.0 version, which will have nothing at all to do with the current version, but for now, they just plain suck.
