I just thought of this when talking to WolfDoc about how he wasn't cheating (yea, I know, GNU is on a "HE CHEATED" thing, but meh, he knows I'll call him out on it if I think he is)
Anyways, with the IP database, if you get a lot of IP's in your database, it makes it easy to get IP's of someone your looking for. Now, many would argue that this is a good thing, and I agree, it'll rock to find someone when they changed their IP with one or two purchases. The problem lies in the fact that the defender has no way to prevent this, which is where this Viii comes in. A cat and mouse game in heavy favor for the cat, of sorts.
Now, the DBOB will run in the footsteps of the MOB and MLB. It's a Malware-type viii that will do damage to the targeted users IP database, effectively overloading it and causing some of the tablerows to drop, depending on time ran and version of the Malware. Now, for how utterly powerful this is, and how it can take the top placed player out of the equation fairly quickly, you can only have one active at a time.
I know this seems like a cheap blow tactic, but look at it like this: If I wanted to slow down my attacker, I would have to do something to make them need to regather themselves. This would effectively do that by both them needing to re-purchase IP's and waste time doing so.
Tell me what you think
