Well,
M45h is a pretty new account, but he's only played one game with
sandman175, so surely if
sandman175 was using a second account to gain points he would have joined more games? Most likely, it would have been done when
M45h was still a New Recruit, rather than fifteen games into his Conquer Club career.
Furthering this point, why would
sandman175 agree to secret diplomacy if he wasn't going to win? If this did take place, then he's ensuring he loses the most possible points. That doesn't make much sense to me.
I'd imagine that you'll receive something along the lines of: "secret diplomacy is very hard to prove, blah blah blah".
