I hate to say this, but do you know who you are up against? Domain squatters are the sleaziest web entrepreneurs known to man. You are basically making their job much easier... If this site gets at all popular, domain squatters are going to scrape your site for domains that have any value whatsoever and register them. That's how they operate. They are set up to register domain names quickly and cheaply, and squeeze any profit from them at all. For example, it used to be the case (might still be) that if you did a search on GoDaddy.com for some domain, and did not register that domain within X hours, GoDaddy would sell their searches to squatters which would then often register the domain you just searched for. My guess is their whole process is automated based on how long the domain is, which dictionary words it contains, etc. Shitty, right? You are a dream come true to them: more than just data on if the domain was searched, but actually tracking non-registered domains' popularities... and posting it for all the public to see! All it takes is one of these self proclaimed "web real estate guru" assholes to come along and see your site has decent domain names listed, and tell his programmer crony to scrape and register them. I see your only option being using images to display domain names, and mangling up the URLs, to hopefully stifle anyone trying to scrape your site. Then, if you have a lack of morals and want money really bad, you can sell a feed of popular domains to squatters from some good money. Good luck.
