Ha, that's funny. This game, you broke an agreement with me around turn 12, with nary a word nor regret. Remember how on turn 2 or 3 you agreed with my proposal that Abysia would hold a demilitarized Feldan Forest since I couldn't realistically use it to stage an invasion of you, but you could of me (just like you did)? Remember how - once your expansion started rolling and mine stalled - you captured it w/o so much as a PM while my assassins were still (messily) working through the Bone Tribe Shamans leading it?
Last game (and I only bring it up because you mentioned "rounds") you stabbed me in the back even as you assured me you weren't and tried to manipulate me into giving you territory to "help" me. You also kept trading with me well after your ostensible allies stopped...
Round 4.26 when I was blessed with you as a near neighbor: more of the same, and a dagger in the back for having played straight with you.
I expect a few of us here remember your R'lyeh in round 4.23. Hell, I remember round 4.23 and I wasn't even playing in that one.
I may be a weasel, possibly even a paranoid weasel, but I'm an honest weasel, and when I stop playing straight it's pretty obvious because my teeth will be latched firmly onto your nape. Mind you, this game only has one winner, and I don't hold anyone's diplomatic style against them personally. We're all going to turn on each other at some point, and our meta has never frowned on treachery, double-dealing, or dishonesty outside of trade. But as you said, after a few rounds of seeing a consistent diplomatic style it's hard to ignore it... and that's not really to your advantage here...
Also, sorry, I'm not the only one with scouting capability, even if mine fly so they might have better range to count what you grabbed. They could verify your expanse as well as I could, albeit most not as quickly.
I'm also a bit shaky on how precisely this was supposed to work out positively for me, and how I was scheming to take advantage of my neighbors as meat shields when none of them were between me and the oceans full of well-armored Rain-bearing toad-men surrounding me. Best-case scenario for me was a strong, angry, vindictive neighbor reduced to merely twice my size that could attack me with impunity and that I couldn't attack back, with one province between their capital and mine and their largely-impregnable oceans surrounding me. Yup, I had so much to gain here...
(I'm tempted to give my post-mortem at this point since it would change nothing, but I have something like 0.125 aces still up my sleeve so I'll hold off. Don't get me wrong, I will without question be dead before winter (probably well before) but there's still a beady toad eye that I wanna try to thumb my nose into...)
