It appears that he did. I believe he posted about it just previous to your post.
The force respider option is gone as well. I can only guess that the last five searches is a study tool for Matt at this point. I can't imagine leaving it in place.
Matt is using a black list he got free from squidguard. I am wondering how many others are using this and what the criteria is to be placed on it. I found sites of ours and others we know on these lists for no apparent reason. There were even some IP's that are on our server that have yet to be developed. They don't even have an index page and they're on this black list. Oh btw, if you have an adult site you're trying to get listed, this would be the most likely reason it isn't from what we are reading on these lists.
Matt: you might want to rethink using this data alone to decide what you do and don't want in your database.
