Invalid Uh, I have a problem.

Hi everyone. This is my first post here in this SteamRep forum, as I haven't got problem so far. But some minutes ago, while I was playing, my friend made me notice that I was labed as a SteamRep scammer.
Now, some weeks ago there was a user who was using my nickname, and who added and tried to scam the people in my friend list more than once. I reported him twice, although it wasn't of any help. I also had a look on the following threads, that were listed in the Additional Info :

He seems to use the nickname of a friend of the victims, so I don't really know if he's a bot, or if he's an actual person, but I'd just like to point out that he's not me.
My account, the one that was labeled as the account of a scammer, is the following:
http://steamcommunity.com/id/mangecu
While the account of the actual scammer is this one:
http://steamcommunity.com/id/215rasdfasfdg/

Now, can you help me in any way? How can I prove that the one who tried to scam these people isn't me? Do I have any chance to get my Rep back? Being labed as a scammer may be a problem for my future trades :S
Thanks everyone :3

I'm such an idiot.
You reported the right guy. I'll now go to my little corner of humiliation.
And close this, sorry for bothering you all because of my disattention :S
