Hi there,

The Grey List on my 3 servers has typically shown 50,000+ IPs over the past few months but it has now dropped to 5-15,000 on across all 3 servers in the past week.

Has something changed?

My guess is the Grey list should be growing in size, not shrinking.

thx
G

Yes, since the end of last week, we changed the algorithms that decide which IPs to block. Now we block more IPs but for a significantly shorter time. We went from 3 days to 3 hours. This is due to IPs changing profiles fairly within approximately 12 hours. We expect it to significantly decrease the number of false positives (captcha passes).

So far we don't see any negative side effect, as malware infection rates are continuing to go down.
