I'm actually very impressed that someone finally doesn't have to have some sort of ego and actually accepts his mistakes instead of making excuses, good job on that Cavik, we need more people like you.
OT: The OP thought the exploit was a part of the game mechanics as to how you find props because that is how it is in the GMOD gamemode, and clearly thought it was done intentionally. I see why he got so ticked off, but he definitely got way more mad about it than he should have, and that was uncalled for; but the fact that he was permanently banned seemed a bit too much in my opinion, even though I don't host as often anymore, I used to only permanently ban if the person clearly was a troll or just stupid and wouldn't learn from their mistakes, however OP has proven that he knows he was somewhat in the wrong here, so I say unban him and see how it goes.
