I'm wondering if anyone has any insight into users and their thoughts on free domains like .co.cc and .tk.

Do users enjoy the wider selection of domains in hopes of finding an unblocked proxy, or does the general lack of quality and down your throat ads of most free domains turn them off?

I personally like to disallow them, and do currently on two listing sites of mine. I am re-evaluating this though with the users in mind. I know personally I like to see higher outbound hits and better quality proxies, but I'm a webmaster and think like a webmaster.

I was thinking of creating a poll and placing it on my site to get some user feedback.

Anyone have any thoughts on this?
