I wouldn't say so. I'd see it (and if I were to do it RP it) as your character asking the local guards and civil servants of the realm to keep an eye out for the person in question. Since he is a commoner, and thus without many rights, he's unlikely to know that he drew the ire of a noble until well after he's bludgeoned and dragged to his fate, unless your character made it very clear that he intended to do him harm beforehand, in which case the commoner should have done the smart thing and got as far away as his feet could carry him (preferably putting a realm or two between you). I seem to recall it said that any info given by the game is fair, and I see no problem with this use of it.
