These are suspected secret alliance and possibly using multiple accounts.
Suspect users: Danklae, Hule, Eckloon, possibly additional accounts

Comments: Did not make any meaningful attacks against each other during the game. Danklae vacated left territory open for conquest by Eckloon. As it became clear that Danklae was only focused on attacking me I called him out and essentially they admitted to it in game chat. After leaving appropriate feedback - they followed suit with retaliatory feedback and abusive language. A quick look at their game history indicates this as a pattern rather than an isolated event.
Thanks,
