Description: It was reported about 9am EST this morning that one of the community members on our forum flame (Former ESEA Invite player who was also awarded a community scattergun for TF2Lobby) had his account hijacked. The post can be found here: http://teamfortress.tv/forum/thread/796-account-got-jacked-help/1

I did some research and found out that Hellmagers is currently in possession of many of his items (perhaps all tradable items, can't confirm since backpack is private now). This is what I found in more detail:

It appears that his profile became non private temporarily which allowed TF2Outpost to grab the items new IDs and who owned them.

The account has been returned to the original owner after he sent an email to Robin Walker.
