I have noticed that there is content available via LimeWire that mentions not only pedophilia (or ped/s) in the title, but ages of young female/male children under the age of 12 years old with serious inferences of sexual activity by the minor. WTF is going on here?

Why are files with such blatant advertising and content allowed to be shared via LimeWire?

I believe this is a serious issue, that needs to be addressed. Sure there's porn and sex content - couldn't care less - each to their own. BUT when it comes to young children being abused, and openly advertised here, it annoys the crap out of me. It's irresponsible, and should not be tolerated by anyone.
Is there no way of regulating these types of files to stop them being transmitted around the world to other pedophiles?

Personally, I think pedophiles need some serious help and support, and there are places available to do that for them. For Example, presently there is a hospital in New Zealand working with pedophiles to try and understand, and help them change their damaging behaviour. So they can lead productive lives without hurting themselves or anyone else in the process.

I do not believe this is as simple a matter as me changing my personal filtering preferences. This is a whole different ball game, and the transfer of such files needs to be halted by LimeWire as soon as possible, if possible.

What if anything can be done?

Cheers
