Safe nodes...
1: Shut-down AIRcoin wallet.
2: delete "peer.dat"
3: add these nodes

addnode=107.170.20.200
addnode=188.226.182.21
addnode=54.186.33.252
addnode=75.151.232.141
addnode=188.165.194.96
addnode=5.250.177.28

This will not stop them from connecting, but ensures that you have some safe nodes, so those rogue-nodes are not the only ones you find.

Nice program... PeerBlocker... (Back from the days of winMX. lol. Still works great for many reasons. Nice blacklists too.)
