I can't prove anything but the last time we've brainstormed a brand and domain name, within a couple of days ALL of the name variants we searched for (which were free at the time of first search, and we did the search on an EU service) were taken, registered to GoDaddy, and a "helpful representative" offered us to buy it off them for like 150x the retail price.
The more people use tools like this to spam the squatters, the better.
