There is one easy option, and that's dont download porn from the gnutella network. Just download from a TRUSTED source ONLY. I download mp3's and video's all the time and ive been useing limewire for the past 3 or 4 years now and ive never come accross anything like this being mentioned. Then again i've not downloaded porn using limewire, just use site's like porn hub there's something there for everyone except kiddie porn. That all i have to say on the matter.
