I reported one of these expressions and one "administrator", romanian too , send me a message that I'll be blocked if I will continue to do this. He doesn't have a name. Anyway, sorry guys, our "culture" is improving, but not all the people can follow, unfortunately
Here, "lui" is not a possive pronoun, but an indirect object pronoun (stressed form). Usually, the unstressed form comes before the verb ("i-am dat lui") and the stressed form after the verb ("i-am dat lui").
