Thanks for the reply, I’m already using the JTC captcha, so not sure why you gave me the captcha rundown. I’m not looking for captcha-plugins or even captchas themselves, as search engine spiders/bots are hitting my site en masse.
Maybe I haven’t expressed myself well, I have BPS pro and the security side covered, but that doesn’t help with these crawlers. They don’t care about any kind of forms and aren’t trying to auto-populate anything, they just hammer the server by crawling thousands of pages. My CPU is constantly at 50% and even though I have a high bandwidth allowance, they just waste a ton of resources.
Since I only want to focus on Google, Yahoo and Bing, I want to block all the others. I’m sure a captcha won’t make a difference in that case?
So is there a way to just allow those 3 and automatically block all others, or not?
