Unlike Larry (and others) I DO want to block the vast majority of the

I'd rather have a blanket block rule with the ability whitelist the
handful that might be legit.
Be careful about doing this for the long term. I think that spammer
exploit new TLDs because they know that many anti-spam systems don't
account for them correctly at first. (and/or maybe they are cheaper at
first?). But in the longer term (years down the road).. they tend to
move on to other ones, while the legit TLDs slowly increase. So this
strategy can backfire in the long term. (but, of course, MMV... and some
smaller hosters don't have to be as concerned about a few extra FPs)
