Looksmart has as much spam/junk in it as anything else out there. For instance, I have a client I build sites for who has enough money to do whatever he wants. He hired me several years ago to build as many different looking sites as I could for him because he wanted to have as many spots in Looksmart, Yahoo, and DMOZ as possible. I can tell you he still has multiple sites in each of those directories I just mentioned. My point is the directories are full of deception as much as any other Search Engine.
