Dear TJayYay and all,
I will summarize our discussion about this issue.
TJayYay found the following access in “Live Traffic” of Wordfence.
`Gelsenkirchen, Germany arrived from https://*****.com/ and visited https://*****.com/
12/18/2015 7:59:10 AM (7 hours 37 mins ago) IP: 80.134.***.*** [block] Hostname: *****.de

This access was a kind of referer spam. Unfortunately, IGB currently does’t block this kind of access to the “public facing page” (e.g. “front end”), but blocks an access to the “back end”, because that’s the current concept of this plugin.
But I really appreciate what you raised in this issue, because I can know many site owners really want to block both “referer spams” and “malicious accesses”. So I should keep going to improve the functionalily of IGB for our ideal goal toward the futre.
Thank you!
