Since you asked me nicely i took the time and viewed the entire replay.
1st of all only slark and viper were locked...and only these 2 play together. (checked they're matches)
Enchantress and leviathan are just some random guys that got nothing to do with slark and viper.
Excepting the moment when at 4:20 viper backed off before slark announced SS Nevermore (which i think it's nothing strange cause if they play together they talk on skype or maybe same room) ...NOTHING WEIRD THE WHOLE GAME.
They missed a lot of ganks, a lot of stuff, they died stupidly.
NOTHING MAPHACKISH ABOUT IT.
So...as a conclusion...THEY MADE FUN OF YOU GUYS.
And the fact that traxex who finished 1-13 and got violated the entire match asked them if they got MapHack...which is normal for a guy frustrated of loosing with a simple hero like traxex...means they made even more fun of him.
Ok, now i hope you're happy, although it's not what you expected but eh, that's life my friend, it's ups and downs, you win some matches and lose others.
Case closed! None of them got MH.
If you consider i've taken a wrong decision feel free to send this topic to my superiors, but i won't ban them just cause they said they got MH but didn't prove to use it.
