For all my interactions with Emilio he has been a stand up person. I'd vouch all of my 2p2 and poker rep that he will not angle shoot you in any way. I'm sure you'll find plenty of others on this forum who would do the same.
He's a very confident player and likes to exude confidence in his public persona online (who doesn't for that matter? Much easier and more fun being big and macho online than in real life
) which I'm sure is why he has sounded so eager to take you up on your offer--remember that you attacked his rep and skill by posting those things about him, so clearly it will make him more emotional and more willing to fight vs you.
Plus, look at things from a more rational standpoint--I don't think any high stakes reg would want to be complicit in scamming someone and use up their time and risk their rep for someone else--it's too high risk and we're all either to selfish to do it for someone else, or too selfless to do it to scam someone else.
