"Stop" what, exactly. Crusading for fair play?
With a little thought, it's pretty simple to piece together most of what would probably satisfy most people here.
1. Much of this thread has been about researching & exposing the truth about Kip's cheating. ALL the cheating. So, to address this, Kip would probably need to publicly come clean about all the cheating he has done. Once it is ALL exposed, there would be little else to research. Make sense so far?
2. Another key theme of this thread has been to try to prevent future cheating. So, for Kip to "stop" tihs, he'd need to, um, stop cheating. Obviously, people will be skeptical of Kip's future performances so it'd probably help his cause to publicly announce his future races (at least for a little while) so anyone who wants to tag along/monitor can do so. Doing races under aliases, etc probably won't help "stop this". Still with me?
3. Returning the prizes & prize money from races he cheated at, so the people that earned it receive it would be a good third step.
There might be more, but those are the first big three that come immediately to mind when I first thought "what a stupid question" after reading your post.
Now, of course if by "what would make you people stop", you were referring to the non-productive posts about compression socks, etc.. I have no idea what's going on there. Those people should probably stop. Fiber might help.
