If your WordPress becomes more popular, it’s also the time that you have to fight more and more spam. It’s not only about all the spam comments you have to moderate, but it’s also hard work for your website’s server. These spam bots are not playing nice and might “fire” multiple comments within seconds to your website. With the result that your website becomes slow and is maybe offline after several minutes. I tried a lot of tweaks to keep my Web development blog clean and fast and after several upgrades and modifications I found the 5G Blacklist (don’t worry about the year, the list still works). It’s not a 100% solution but together with my current web host and the Bad Behavior Plugin, my website becomes much faster the last weeks.
What kind of action do you take to fight spam bots?
