I am not a spam bot - RefControl Users..

If you're entering a comment on a blog (e.g. for Rafflecopter entry), you might - like me - get a "You seem to be a spam bot" message (even after ticking the "I am not a spammer" box). I turned off RefControl and resent my comment, and it worked fine - guess it looks for the exact referrer address, when verifying a comment.

Yes, blogs tend to be extremely referral-centric. I have had a couple of sites that won't work properly with Referrer Control, but the vast majority have been fine.
