Lucy - by "security logs" I mean my "gotcha" logs that record baddies - home grown. Sorry if I mis-led you.
I block a lot of translates more or less accidentally. Something comes in on a G IP that's bad, it gets blocked for x hours where x increments if it happens again before the timeout. Apart from a few IPs where I get most of the translates, I have now blocked most of G apart from the genuine googlebot; unfortunately my clients want to be seen in G's SERPS. Sad but true. :)
UK is, er, UK, where I live. UA is Ukraine. Although sometimes it's difficult to tell the difference: there are a LOT of idiot Brits who are careless about what they click on and seem to take ages to get rid of viruses, even if they find them in the first place.
I met one such idiot whilst buying a mobile broadband dongle in a local shop. While we were waiting to be served he told me about this laptop he'd just bought secondhand "in a pub". Used up a whole 30G of mobile bandwidth over-night, said he'd found a lot of viruses, how could he get rid of them? When I said he should get professional help he said he'd just buy another 30G's bandwidth - couldn't afford the de-tox.
