As an experiment I setup cloudflare for website of mine which gets majority of its traffic from Pakistan (where I am located). This is what I see https://dl.dropbox.com/u/8037186/cloudflare.png
It basically shows cloudflare marking 100% of traffic from Pakistan as known threats.
I would be interested to find out if its a common problem facing users from this region / other developing countries?
We commonly have shared ips in Pakistan could this cause cloudflare false positives?
Any suggestions for avoiding the captcha?
