Using Redis we block IPs who accessed our website more than X times not logged-in (200 URLs right now).&lt;p&gt;We also had the requirement that all good bots(Bing, Baidu, Google) should pass-thru without blocks or any slowdown.
Another requirement, was that those good bots should be verified(Reverse &amp;amp; Forward DNS Lookup) before entering out good bot list.&lt;p&gt;It is working great for our high-traffic website ( 2 Mi hits&amp;#x2F;day). You can check our work here:
