This guy is trouble in any group that you have, he comes from MSN,and it is in MSN that he is causing problems. As far as I know he causes no problems in yahoo.
18.104.22.168 this is his latest IP Address if you show full headers on the email application it will tell you the originating email IP. He tried to report me to msn and then I turned it against him ,because his last email as Matt and as Theo Lost were from the same IP Address. Busted
All these are his MSN Nicknames. Well he disguises himself as women and as other people and disrupts your groups. Well if you do not have message approval on your group, turn it on. I think that the approach to this bullying has to be approached from a different perspecitvie. You can not keep them out forever, but when you allowed them in you can monitor their messages forever. Yahoo provides such a tool and MSN does as well, with this tool you can have a member on moderated status forever. This is the solution in my opinion!
His email addresses are
"From: "Matthew Provencher" email@example.com
By midnight tonight, June 30, 2007, I will have deleted all email and contacts from this address, and will stop accessing it. Any mail received here after midnight tonight will be filtered as junk and deleted w/o reaching me, EVER! I've tried several times throughout the month to re-establish contact and a possible friendship with you, but you have not replied to any messages."
