You have been on the server long enough to know the rules, not only that but you attempted to pearl into an active trade, attempted it more than once and then tried to pearl into the middle where the items where. Be it out of curiosity or what have you its no excuse not only that but as mentioned done during a trade which has malicious intent behind it as the items could have been stolen,no matter how you may look at it it would have been a mess to deal with.
It definitely deserved an outright ban and the other staff seems to agree.
You will be unbanned in 5 days see u then
