No one can really say HOW high a risk a certain plugin or exploit is as none of us work for SOE. Usually, the more outspoken, overabusing people are the ones who get busted. I have been using this since it has come out and have had no interaction whatsoever with any GM's. Now, if youre going to use this, then use the equip any item hack and have a necro running around wearing your warrior mains qvic armor, then yeah..expect to get busted lol.
Remember, once you run macroquest and click that EULA accept button, youre in violation (no matter how much those at the MQ board say its a "passive" hack) and can get suspended or banned. Caution, common sense and silence are our best weapons..other than that.. who knows what theyre capable or not capable of tracking.
