Are you saying that you are currently muted and the things you "said" were via quick chat? If so, I don't think you have any reason to worry. Even if they weren't quick chat replies, they aren't breaking a rule - unless there is a rule against using non sequiters.
Using Magic Dart at Barrows would be even better. Any reason you don't want to mage that iron dragon slayer task? Say, using chaos gauntlets? Just curious.
