I've been seeing a lot of verification visits over the past few weeks. Since they do not come from valid bot ranges with approved rDNS they've been blocked.
I particulary will not enable 126.96.36.199/16 - I've just posted the reason in another thread: look up mocality.
It is quite possible my sites are gradually becoming unverified - I haven't returned to WMT for a couple of years now and have no desire to do so.
