Those "You're Richer Than You Think" ads from the banks are worse, as these are targeted at getting people to borrow even more debt against their house and other assets, which is pure evil.
The one good thing about it is the fact that its letting all these domain owners out there know that these domains have aftermarket value. So it is bringing awareness and education to the general public. So that is a good thing, I guess. I say I guess only because I find their valuations very low compared to my sales.
