It's two things Gene. The first is that there is no difference between the "contains some words" and "contains only words" check boxes. I just searched both using all TLD's over the past 24hrs at the results were the same for both; 15 dictionary words. Secondly I just did a strickly dot com search of dropped domains within the past hour and 362 results came back. All were beginning with the letters "g" and "s" only. What about the other 24 letters? I then searched dropped domains that begin with "w" using the same search criteria and 18 results came back. How can this be? There is a search result limit of 2000 which is understandable but I was well within the parametres and the 18 "w" domains should have been there in the original search. Normally this wouldn't be a problem, just time consuming, but since Justdropped is charging me by the search (500 for $10) I want reliability.
If I have to add a third issue it's speed. This experiment I just did took about 20mins to wait for about 10 pages with several "timed out" screens.
