Checking the status of immigration blacklist

Sir, I need your advice.

I was in Abu Dhabi in 2003. I came on a visit visa from Oman, without permission I enter Abu Dhabi but I don’t know about the permission, one agent was cheating me.

Abu Dhabi police caught me and also ordered deportation. The passport was stamped (Not allowed in the UAE from this date). l want to know whether I am still blacklisted or not.
