I've just turned down a site submitted to Travel Lists.
It reminded me that it doesn't happen very often.
(...thankfully!...since current policy is to refund review fees - I don't like telling people their site is not good enough to get in, and taking their money too!)
It's interesting how self-balanced the submission process is. I'm surprised that we don't get more unsuitable submissions - we certainly get loads of unsuitable link exchange requests. (All, like the one a few minutes ago, are instantly deleted - see simple policy).
It's as if only companies that are confident of their 'product' bother to apply for review, which is perfect from my point of view.
