OldFrog75, there is no 'gravitas' other than the same amount of gravitas you place on it. A lot of folks will say, "It's the internet!" as their answer and leave it at that. I know you're older and I totally get your 'conscience twinge' about this. Don't let that stop you, because of worrying about their feelings about being banned.
HoppingJalapeno and DaRock both have the right of it. You aren't going to get them banned. Your reporting of THEIR ACTIONS will possibly GET THEM BANNED.
That last part is important: Their actions will get them banned.
There's one other aspect to all of this that most folks don't think through: reporting them is the ONLY tool you have at your disposal in this environment. If you don't use the tools available to you, then the folks that do these things continue to walk completely unscathed to be free to do what they are already doing -- and I'm sure they think they are having a great time messing with other people. At least mark their path for the staff so that when they do get the incident that gets them banned, there will be a long list of complaints and reports that track with them -- which is exactly what the WG staff need to make a ban stick -- more than one incident on the books.
Meanwhile, I think, in all honesty, too much time is wasted worrying about hurting someone's feelings (by people who actually care about other people, sight unseen) when the thing that is really important is that those folks are ruining on purpose the enjoyment of others. Hurting their feelings should be the last thing on your mind. Report and move on.
