I noticed that the "Proxy" filter is no longer available?
That may be problematic for AWeber users?
Aweber has a hard rule that they send back a captcha for same zip address in 12 hours I had a recent run where 25 of 40 ouniwue visitors got the captcha (I can see in the right side of dashboard) and as such did not get added to the list.
I think if that filter had been in place this would not have happened?
I cannot think of any other reason why so many got the captcha.
