It’s not a big problem with DNS, because it grew organically, becoming more popular as it became more widespread. We don’t have that luxury, and as a result if we don’t combat squatting, it will strangle us in our crib, polluting the namespace to the point where nobody can use it usefully.
Names that aren’t bought will become available using the (new) regular registration process - just pay a flat fee to reserve them.
In the proposed second-layer dispute mechanism, anyone can set up their own blacklist - there’s no single canonical one everyone has to use.
Expanding the auction time gives people more time to become aware of the ongoing auction and to participate. Likewise, expanding the reveal period gives more time for people to seek help with revealing if they need it.
I don’t think this is a good idea, as I don’t think it materially advances any anti-squatting goal, and incentivises people to try and deregister and snap up names again to reduce their rent payments.
I’m not ready to abandon preallocation so easily. I think it’s likely to result in a lot more names going to those who will actually use them.
