I wonder what type of "Tor exploit" this is. The first thing that comes to mind is hammering the intro points. One solution would be to increase the number of intro points. There isn't a config option for that, so you would have to change the Tor source code and build your own version. However, I don't think that's it, since that would only affect establishing a connection. After that all clients would be routed through rendezvous points distributed across the network, which doesn't explain the slow loading even after you're connected. kmf, any ideas? OTOH, is he sure it's a Tor exploit and not a server exploit, resource exhaustion attack, or something like that?
