Todd Mintz raises an excellent question.. Selling TM intent domains has been going on since before Michael Arrington was the CEO at Pool. I suspect it has less to do with "design" on Pool.com's part and more to do with the sheer volume of names expiring. You can only prescreen so far. Still, a rudimentary filter or diclosure relating to trademarks would not be that difficult and would probably help as this industry matures.
