Sounds like your props spawned under the map and you might not have noticed the shadow of them under the ground and just kept trying to spawn them in but they kepted spawning in under ground so you didn't see them, I have seen this type of thing happen many times and it has even happened to me. It seems you didn't mean to prop spam you just thought the props didn't spawn in do your kept trying then you got banned for prop spamming when you thought you didnt even spawn in a prop.
But if you are lying then you should get denied but we will find out when someone talks to walt3r.
Good luck
