I joined a pos ladder ffa, and we started with 3. The other players were Nigg(A) and Bang-Bang.

After a few minutes I see orange blatantly build hacking.

Here orange targets my only outside peon going to bl for an expansion. He's also ogre-magi.

After I stop his lust attack on my base, I hit orange. Blue convienently goes straight to my base without scouting.

I've already taken out orange's barrracks, and im going for his hall. Blue stops his attack on my town(I have a cannon), and goes to help orange. He also exps to tl.

Orange apparently doesnt have enough resources for another hall, and attacks my remaining grunts with his peons. I send all my grunts to tl and break in, while expanding to bl. Bang-Bang. probably knew his ally was going to lose, so he left.

Nigg(A) had no intention of going quietly, and used a drop hack to give me a draw.

They were both quite obvious about doubling me, and in addition to orange build hacking, I believe they both maphacked.
