I'm not a prolific poster but I have been a member here for many years and for the most part this place is pretty tame,but from time to time I've seen things posted that bothered me.Like @bmudd14474 said use that flag button and then move on.
I can speak from experience as to how bad things can get on an online forum.I was a LONG time member of a fishing forum that was specific to my region and this place was a bastion of great information and camaraderie until a political sub-forum was added and it all went downhill from there.Friends became enemies,incredible amount of verbal attacks,threats of violence etc.It was very hard not to get embroiled in it because a handful of a-holes would attack anyone if you didn't think/believe the way they did so I eventually asked the site owner to delete my account as it was no longer worth being a member and the crazy thing he still allows it to go on to this day.
There's a forum for every subject under the Sun and we all know SMF stands for.Lets get back to smoking and helping ourselves and others get better at it.
