At this time we have just recently become aware of this, as of now the IPs they are using to flood these results are being blocked by using our Block list, so if your using that in your Peerguardian or using the .dll patch your doing your part to block them.
Right now this appears to be some sort of test system in place, its not 'flooding' reults to the primaries such as some of the other methods they use are although, these are definatly fakes, at this time they are using several 'Full Paths' and the only way to filter these would be -aaaabbbbcccc111.
As I said the -user filter is definately the most important to use at this time as its got enough results when it shows up in searches to kill the primaries connetions your networked with..
We are keeping an eye on this and thanks MinMxFan for helping us to watch out for new and unusual tatics ..
