TNA has restarted the Gut Check Challenge with a better voting system they claim (the old one was spammed to a cold, dark grave by bots.)
You can find the participants and voting here.
People who are gone from it now:
Some of the scum who botted the old one.
Sami Callihan
Luke Hawx
Sugar Dunkerton (fuck you TNA. Fuck you).
So go check out the profiles and vote for those you feel should have chances on Gut check.
