Hi, guys
I was at a conference last week put on by GMAC and they told us they've sued Scoretop. One of the reasons is for hosting "live" GMAT questions (that is, questions people actually saw when they went into the test).
The GMAC people told us they are trying to identify users who post such questions and both ban them from taking the GMAT and report their names to business schools! They may also do the same to people who discuss or respond to such posts.
So DON'T read or respond to such posts, either on Scoretop or anywhere. If it were me, I'd avoid Scoretop altogether, just in case. (This is my own personal opinion - not official MGMAT policy.) At the least, if you see anything anyway that claims to be a "live" question that someone saw on the real test, run the other way. (Virtually, anyway :)
