Until recently, comment flag type did not matter very much and as moderators we basically processed them regardless of type.
As a reminder when flagging there are the following options:
From here:
- rude or offensive — comments that violate the “be nice” rule
- not constructive / off-topic — comments that do not contribute to improve the post are ripe for deletion
- obsolete — for example, criticism of a post that has been satisfactorily addressed by the author
- chatty — anything that's not really relevant (e.g. “+1” comments)
The reason I am mentioning this is that Stack Exchange now automatically generates a flag for moderators if anyone has a fairly low threshold of rude/offensive and/or "not constructive" comment flags. For example, if someone flags enough of my comments, as moderators we will have to review an automatically generated flag.
Because of this, the moderation team would appreciate if comments are flagged based on the above categories. Understandably, the difference between "chatty" and "not constructive" is fairly subjective and generally speaking, it's fine to error on the side of "not constructive" if you aren't sure.
But if comments are primarily "too chatty" please use this flag type.
Any questions, feel free to ask.
