When reporting, there are two options, spam or other.
I rarely see spam (though that could be that MNHQ spot it themselves or posters report it super quickly) and so generally use the 'other' and then explain why.
I wonder whether it might make more sense for the reporting to be along the following line, say:
- spam
- troll hunting
- troll
- personal attack
- other
These are presumably the most common reasons for reporting
