Fortunately, it’s easy to get back control. Modify your hosts file (/etc/hosts on Mac/Linux; uh, someplace else on Windows) and include the following lines:
127.0.0.1 tcr.tynt.com 127.0.0.1 spa.snap.com 127.0.0.1 shots.snap.com
If you are using either of these services on your own blog or website… please stop. It’s obnoxious.
