No, it's much friendlier. When a wallet node receives "bad data" from another wallet node, it flags the node with a DoS score. When the score reaches 100 for a given node, it is removed from the list of reliable nodes and is no longer communicated with. That information is stored in peers.dat, which is why I recommend removing it when upgrading to 2.0.4.

If anyone is still running 2.0.1 (which apparently is the case), and they got the wrong 2.0.1 interest awards, what happens to those awards? Will they be confirmed?
