The network is being attacked by companies/whoever....clogging the network with dud files...when you discover ....a dud file ie it is something else or doesnt work trash it please get it off the network!!! "They" are trying to corrupt it....real conspiracy...at work here.

Depending on which p2p app you're using you can filter many if not most of those dud files (spam) out. For example, I filter out .wmv, .jpg & .exe

You'll notice each search you do gives replicated results. These more often than not come from certain T1 sources. Filter out the above words & you should find they no longer show up in search results. Of course you can add/remove filters anytime as it suits you.
