I apologize for going a little off topic here, but there is something I wanted to share with you guys. Last night, someone rolled up an alt account in order to send me a harassing PM. I'm not going into further details, but I wanted to tell you the steps I took to make sure the mod dealt with this person swiftly.
Before I continue, one thing I would recommend for the newcomers: Go to your profile, and edit it. There should be a way to set up your wall to where you have to approve of any comments.
Okay, this is what I did to get a swift mod response. Now, I can tell you right off the bat that your first temptation will be to delete the PM/comment. Don't. The mods will need it in order to track the harassment. Send your report.
Then, you'll probably be tempted to yell right back. Don't, because that will make things worse and possibly cast you in a bad light. Instead, what I did was simply send them the following message: "Reported for harassment. Do not message me again." Then I put him on ignore, which should be your next step.
Now, from here you can do a couple of things. Either:
1) Check their profile. If they have it set to "Show recent visitors," you can tell if a mod has stopped by. Or:
2) Leave the message undeleted for about 6-8 hours to make sure the mod sees it. They will not tell you if action was taken against the person reported.
When it doubt, try to keep your cool. It will get your report in faster, and will make you look like an adult in the process.
