My thought process is that people who want to make ban bets already have a long history of bans and probably have nothing to lose because they may just end up getting banned for a real reason anyway. Normally, I think ban bets a ridiculous and really a terrible kind of bet and a waste of the mods time. You can literally just leave the site for a certain period of time. People who take the bet may even plan that out. A ban bet only satisfies the notion of making the other suffer, not show a sign that he was wrong like having sig control.
However, considering the thought process I just mentioned, go nuts. I noticed a scenario not to long ago where someone was making wild claims and that person refused to address more than several comments that clearly disproved his comment, and only aimed from the ones that could be up for preferable debate. In that person in that scenario made a ban bet and lost, then yeah enforce because chances are they may try to weasel out of it.
