Is someone trying to bring down all the pools? Maybe so that some of the large miners (VPS and botnets) can run private pools and dominate XPM production? Can someone who knows where to look if there are unidenfied large XPM miners?
If this is true, what you are saying, then the pool operators might sit together and share some experience / information about the attacks to sort things out. it could be useful. i’ll be here.
at least ypool’s webpage seems to be ok: their impact on the primecoin network is huge…
