So lets say im getting boosted from DMG to LE. He gives me like 5 - 10 wins till Im LE and after that I play there legit and win, maybe also getting ranked up to LEM, whatever.
So what Happens if the booster then gets VAC banned? Maybe next week or maybe in 3 months...

Some people told me that the boosted one will be unranked but after 1 win be about the same rank again he was boosted to.
But isnt it going to be reverted ? I read that all wins will be lost... So am I going to derank again then?

All this boosting services wouldnt make any sense then because every cheat gets detected one day.
