Bearshare DDOS'ing Webcaches

[Neglacio]

Beacon GnutellaWebCaches (GWC's) like the one here are able to log floods and poisoning attacks, mostly performed by anti-P2P companies.

Beacon already has a DDoS security, but still one of them has fainted, and the others are under a heavy attack.
Why?

Well, out of nowhere, all clients with the Bearshare vendor (so not the iMesh clone) are crazily connecting to GWC's. This causes a lot of stress on them. I, myself, have a Beacon cache that doesn't have Gnutella enabled and only G2 (Yeah, sorry). Still, Bearshare's are vastly connecting to my cache.

This flooding really come out of nothing. Newer versions of Beacon will include a full block for Bearshare's until it is solved.

Why is this happening? Is it similar with the island Limewire "virus" from their developers a few months ago? Or is it an exploit found by the anti-P2P?
What are the stats of this on other GWC's and UDP caches?

Please, answer this. If such services fail to work, Gnutella may possible die down, because this is it's weak spot.
