I was going to advise Dino not to try it on, but it's down to to personal choice.

In fact, you did so in your penultimate post. His initial post re his teaching in Thailand made it abundantly clear he'd been working there illegally. I thought that was bravado, and then he chose to praise up his CV. Red flags in my book! Ok, that convinced me that maybe all is not what it seemed. Could be a load of bollocks as far as you and I know.
By the way, I know of a long-term 'visa cheat'. He cares not about warnings like yours. That's his choice too, as it is Dino's. Persomnal choice, that's the crux of the matter!
