I just am posting them as try them out to be sure it works ok. But that doesn’t mean you need to always change to the latest even one or two back is good enough. I just do this so if someone wants to try it they can. Unless there is a site someone wants me to check on to see if there are annoying ads or popups or redirects that needs looking into.
I update every other day on my systemwide hosts file (from hphosts).
The giant fraud, phishing, and malware specific lists on hphosts are updated just about every day. The other ones such as fakepharma, warez, etc … are updated less frequently.
