I will chime in.
I was "brown's" ally for much of the game. I'm pretty sure that whatever roadkiehl experienced, my experience was 100x worse since we were teamed and coordinating strategy.
"I send sub to your generator X in case I need it"
"It's just plan b in case I need it"
"Hey you there"
"I need it, drop shield!!"
"I'm about to cap I need it"
"Now I send sub to your generator Y"
"Don't worry it just plan b"
"Okay I need it be sure to drop shield"
"Did you drop shield"
"Did you drop shield"
"Hey"
"U there? drop shield"
"Hey I need your security chief"
"I'm gonna get in war with teal and need the chief"
"Look at his production he very dangerous"
"Please can I borrow sec chief"
"Why you build a mine"
"Don't build a mine! I will fund you"
"9 min left to cancel"
"8 min left to cancel"
"7 min left to cancel"
...etc...
"1 min left to cancel"
"Y u no cancel now I can't fund you"
Even though it's far from my best self-interest in terms of winning the game, I've decided to attack him. He has now finally stopped messaging me. I'll probably lose my chance at top 3 for the decision but honestly it's one of the best Subterfuge decisions I've ever made.
