If you were actually abusing the drawing in this way, I certainly feel no sympathy for you. People who play on multiple accounts to win more in drawings than allowed in the rules aren't screwing the casino. They are screwing the other players who would have won those other prizes. If people were cheating in a drawing but happened to be 100-year-old amputees in wheelchairs, should their cheating be overlooked or should they be 86'd? I vote for trespassing.
If you weren't cheating the drawing, then it's unfortunate that you put yourself in situations that made it look like you were. But I would chalk that up to poor judgment on your part, not the casino's.
I'd apply the principle of being careful not to look like something
