First of all, my friend declared an open alliance. If the rules applies strictly, that IS allowed.
Secondly, if you look at the game log, I had no evidence of an alliance and neither did the other two. So, again, a report of a 'cheat' that did not happen.
Thirdly, if you look at the chat log, he condemned us for being cheap. May I ask whether such an insult (Yes, it IS an insult) can be tolerated on a community website like this?
Fourthly, unrelated to this report, if the people who created this would actually give an option to OPT out, that would be a very nice addition to an excellent service
