Hello. In a game I am in, I am Mexico. I expanded for a bit, and eventually reached Peru's borders. I thought that Peru was inactive, so I began making plans to invade Peru. Then, Peru messaged me, and told me to back off. I did, but warned Peru that I would eventually invade him if he didn't join my coalition or ally with me. Then, Peru kind of started flipping out. They said that I would regret it if I invaded him. Then, when I kept my offer to ally with me, Peru began threatening that their one goal in any future games we played together would be to take me out. He began to also threaten taking out Canada, my ally, in any future games. When I write messages, I sometimes write in the third person. For example, in this game, I wrote, "It is best for Mexico to attack you, but I won't attack if you join me." Peru interpreted this as me writing as Canada. He began accusing me of Canada being my alt account. He sent this message.
"How many accounts are you playing. You just slipped up thinking you were on Canada's account. I'll turn this into support. Go ahead and attack. I'll hunt the (Canada's username), Brutus Trump and whatever other accounts you are playing in the future if these accounts are not banned. He also said, "Today I don't care win or lose but I'll hunt your accounts down in the future and let others know if you survive a ban." He also posted an article in the newspaper accusing me. What should I do?
