I registered at wp because I saw this topic – I have the same thing, weird referrals from here.
Personally I think it maybe related to semalt: I just got rid of them through some .htaccess stuff. They used to visit me from Brazil.
Now I notice that the pattern for this buttons stuff is: referrer visit from there (Brazil IP), then visit (Brazil IP).
Seems to me that this maybe something to get bypass htaccess things which look for and block an empty referrer string (often used by China bots, so blocked out with .htaccess on smart sites)
Anyhow the other thing to remember is that when you successfully block out sites like semalt they want some other way to get into and look at your site, ie a method like this.
Anyhow think I’ll block it. With 0 time spent on the site it’s a useless referral anyway.
^^ Good thread, handy find. Thx for the UK!!
