I use free Semalt.com monitoring and I do not see traffic from their website in my reports. It looks like it comes up as referrals only in GA. Yes, this mistake is typical of GA and WordPress counter that take up data from Google. You can set up a filter for referrals. There is a special plug-in for websites based on WordPress. The plug-in for WordPress was written by users, that’s why we cannot say for sure that it doesn’t block other bots.
