This is happening because Darkcoin has the same pchMessageStart as Litecoin and Worldcoin so the networks think they are talking to their own clients. Each network should have a unique pchMessageStart but people do not know to change this and then you end up with networks talking like this. The problem is that the PROTOCOL_VERSION and alert keys are also the same. I have been asking Evan for a while now to change the alert keys or when Litecoin next issue an alert Darkcoin will display it.

I have sent this pull request for Evan to pull so that he has the tool to generate the required keys.

https://github.com/evan82/darkcoin/pull/3

I've sent Evan four messages about this now. If someone else could also give him a friendly kick that would be great. If Litecoin send an alert it will be a bit embarrassing.

Looks like he merged it. Did the problem go away?
