If tco is to be the new three-letter agency and gatekeeper, we would like to treat it nice and whitelist its crawler. If tco is inadvertantly blocked, what happens?
I do not know if we have already been checked by tco as I have not sent or received a dm with one of our own URLs. What are the user-agent and IP addresses used by this crawler? Does it check robots.txt? And since, for some, a tco thumbsdown could be a problem, is there a (speedy) appeals process?
