[Salamander8]

I've only done scorched earth once in an MP game, and that was just burning down 2 labs in Sophistry when the massively blessed giants were stomping my Arco butt hard, and even then I am not overly pleased I even did that much. If I ever am in the same situation I'd not do that again (although I did set myself to AI early in Evermore between frustration vs the blessing EA Oceania had and my grandfather's illness cutting my freetime down). I never have cranked my taxes up or destroyed any other buildings just to make my land worth less to an opponent though.

If I feel I am doomed, I do tell anyone I have had positive relationships with that I free them from NAPs and other agreements and that they should consider my territory up or grabs if they so wish. I also give allies/NAP partners my gems and magic items before going out, but not to anyone else. I would rather see an ally get my stuff than my conquerer if at all possible, but I don't involve anyone beyond friendly powers to do so.
