Event views generate infinite links: robot paradise, server hell. How to limit followable views?

My company's server hosts a lot of Drupal sites running Event and lately we've been hit really hard with indexing spiders and robots iterating through huge numbers of links generated by Event views (i.e. from month view you can hit "next" an infinite number of times as well as "previous", AND you can also get to week and day and do the same for those!)

We have put up the temporary hack of disallowing robots from /event/ completely, but some of our clients are very interested in SEO and for some of them up to half of the verbiage of the entire site is in the form of events, so disallowing /event/ totally really hurts our ability to get our clients good SEO.

Is there/can there be any way to limit how far in the future/past one can view? For example, to totally disable week and day views, and then to further limit viewing to months <= say, 3 years in the future or past. That would limit the links generated from something on the order of infinity(gimmel) to something on the order of 72.

Thanks in advance for your time and attention.
