I have one of my sites that is showing users registering, even though I don't have a form on my site. I use StatPress to look at traffic details, and I notice odd sites showing up, saying they are linking in to my site, but I go to those sites and see nothing but garbage posts not related to my site at all.
I am wondering if these "phantom" user registrations, many of whom show the same first name "hunar" followed by @ then a site name, are behind all of these. Also, along with referrals coming from these unrelated sites, I show in my stats that robot.txt was accessed, but I can't find in my file manager for my site any robot.txt file.
Hope this question/scenario isn't too vague, but I'd like to clear this matter up so that my traffic stats show a clear picture of what is going on with my site, and I don't have any slimeballs piggybacking on my hard work to peddle their garbage.
Any thoughts are well appreciated!
