More the charms people sneak in that are the ultimate factor, I used to put these on years ago I've seen literally every way you can mess with them lol
I did theorize one clean way to do these, and have not put it into practice yet, figured I'd share my thesis.
1. No prize, this should eliminate cheater prospects.
2. Heavy entry fee, like 250fg each. But at the end of the comp everyone gets back their entry fee 100%.
3. Must be in this order: Enter game, walk strait to moor entrance, Screenshot stash and email to leader. Once cleared, moor entered and wait team.
Again I hope it works out well, if you put these guidelines in order it should be a good time. Good luck
