i am not sure who is "trolling" and as all I have seen is the occasional poster, myself included, join in the convo and then a new guy that keeps talking about Harrisburg as if he is the wrong forum. This "you are in the wrong forum" stuff is for the birds in most cases. I will only speak for myself when I say that anyone from the MA, NE, NYC, anywhere...is welcome to contribute to any board I am part of as we are all here for enjoyment of weather tracking and such...especially winter weather for those here now.
If someone from another forum is always coming into sub forums and trying work up the crowd that is not totally cool but as you stated I have not seen that and that would be what I consider trolling.
