So what are you proposing? That we just continue to allow low difficulty networks to be exploited by people with large amounts of hash to throw around. To let them slowly make us not liquid in a bunch of alts and bleed BTC from unsuspecting users? And I suppose we should also have to cover this all ourselves rather than address the problem at hand?

Or, we could start delisting these coins that have demonstrated that they are unable to sufficiently secure their networks so that we can prevent ourselves and our users from losing coins.

If you don't understand the reasoning behind the action we're taking then you don't know what the fuck you're talking about.
