It can be a little of both or either one, depending upon the quality of the IC part of the tag and the wording of the OOC part of the tag, and how often they do it? At least in my opinion. If they don't do it often and the IC part of their reply is good (read: written well grammatically and engaging) and they don't stick an OOC comment in there all the time it can be endearing and show creativity. On the other hand doing it too much or doing with lower quality IC replies can be annoying.
