LinkFBI Blacklist Checker

I'm an SEO consultant and I maintain a publicly accessible list of domains that I have analyzed and determined to be spammy, malware, etc. and therefore should be disavowed. This extension checks the subdomain of the current page against my blacklist, and if it's on my list, informs the user (in a popup) of why I blacklisted it. The same functionality is available by copying and pasting a URL into this page https://www.linkfbi.com/Blacklist.asp but this extension makes this process much simpler.
