Just ran across something that seems strange and I am wondering if I should worry about it or not, and if so, what should I do about it.
I was setting up an anti spam plugin on my website and noticed in the logs that there was a domain redirecting to my website. It is not in the same niche and I do not own or control it. It is not as bad as an xxx site but it is a niche that is highly competitive and has a lot of spam sites. Part of that niche no longer is legal in the states.
Should I be worried about adverse effects of rankings, and if so, what should I do?
