For all you doubters, perform the following test:
1. Go to overture, be creative, and find say 10 unregistered meaningful two word terms that have some searches (most of the time you won't find anything over a thousand, but few hundred or even few dozen will do).
2. Don't do anything for two days.
3. On the third day go ahead and check these names using Dynadot bulk search (making sure that none of them are registered at that time or recently)
4. Don't do anything for two more days.
5. On the fifth day repeat the step 3. and see how many of these names are registered then?
Do that over time, and puff, the freakish "coincidence" argument dissappears and deliberate pattern emerges.
