Really? Certain tribe? I know at least 4 tribes which didn't play fair since the moment this realm started. But you are right: "What we know and what we can prove are two separate things."
There is another thing we've seen in this realm: at least 3 times 100% fair players were banned for a long time. No scripts, no alts, no password sharing, no cheating co-ops and... no explainations of ban reasons. Yes, you had reasons for another 50+ (just my guess) bans, but...
And one more thing: technically it was the worst realm I ever played for 8 years. Browser version doesn't let you to play fast manually! I can't send more than 45 farm attacks manually: page reload needed. I can't recruit spies in more than 10 villages manually: page reload needed. etc. I send 4 attacks manually in 1 sec with 100% discipline and what I see? 5 sec difference!!!
But anyway I play fair.
No player gets banned without evidence of rule breaking, That is fact. Please do not spread these sorts of misinformation. If you keep doing so ill restrict your ability to further post.
If I am not mistaken plenty of people were banned for rule breaking in multiple different tribes.
And yes, A certain tribe.
