I’ll buy that for a dollar.

According to this post over at the DomainTools blog, NSI appears to be stealing domain name ideas.

This is what looks to be going on:

1. You search (and find) an available domain.
2. You don’t buy it right away.
3. You go try to buy the domain later, and it’s been snatched up by NSI (who are willing to sell it to you — of course).

Sounds like a way for NSI to make a few extra bucks. Used car salesman style.
