Msn Imposters, What should i do?

hey guys, i have recieved a few Pm's here on sythe asking me to confirm trades that i have never made or heard of.

Eg most recent is that im trying to sell a ely for $200 rofl....

anyways, i dont know if there is something im meant to do here on sythe or if there is anything i can do to help prevent this idiot scammed people and maing them believe he is me.
here is a quote from my private messages.

He has actually fucked up there rofl, saying he lives in gorgia, yet my name is " TheAussie1".

My Msn is " [email protected] "
his msn is "[email protected] " (2 underscores).

i have put imposter listings on my MMing thread and vouches thread. is there any more i can do? or anything else i should do?

Cheers
