This is where I was initially. I genuinely thought* that CSTU would need a day or two and then come back and at least address the bet issue. But time for mourning has passed and, again, I think I can speak for the obligees that if he came back and at least tried to work something out since $2100 (sorry, $2200) is a lot of money for almost anybody, that they'd back off pretty reasonably. Had that happened I'd totally agree with you that people are vastly overreaching here.
But, three things, assuming to be true, make it hard to feel badly for CSTU:
1. He's blasted Trump on here for not paying his taxes and for intimating that the election was rigged. That right there sets up a ton of potential hypocrisy should cstu then refuse to either not pay and/or refuse to accept the results.
2. He's bragged about being able to pay at least a significant portion (the $1400) of this bet should he lose.
3. Apparently, he has previously outed other(s) on this site for not paying.
* Then again, I also genuinely thought there was no way all those people would vote for Trump.
