Th8.us was a URL shortener (like TinyURL) that accepted new URLs from 2008 to 2011, but even though it had not accepted new URLs for 4 years, in 2015, my web host received many complaints about email spammers who continue to use pre-existing Th8.us short links in their spam emails, and required me to take Th8.us offline to continue having my other sites hosted with them.
