this is pretty much an engine bug, which admins should be enforcing as 'exploiting' to stop.
Admins need to better communicate, educate and get the word out that this will be punished, and enforce lengthy bans for it.
I used to use tatics like this to walk up thru ceilings (not thru walls/gate..which I consider quite a difference), because I'd seen it done before countless times and admins I had talked to didnt really understand or care. They never updated their rules about it either.
