our site has about 200 to 300 daily visitors. Unfortunately, we get more and more referrer spam (http://en.wikipedia.org/wiki/Referrer_spam) with peaks of up to 350 fake visits, sometimes more, sometimes less.
This makes our statistics almost unusable (we do not publish our stats. Nonetheless, internal “reading” of the webstats is now a pain in the heck due to this many false data).
It is only a few websites who do this at our site (about halve a dozen). Are there any possible measures to exclude these fake visits from the statistics? I think, a referrer spam blacklist would be fine. However, such feature does not seem to be available?
