First of all:
Please read this thread:
https://bitcointalk.org/index.php?topic=260073.0Re-format your OP, make screenshots of the chatlogs, also give a short version of the conversation.
If you do this, maybe somebody in default trust will see your case, and tag the account of TomKoinify (only in case your scam report turns out to be valid... I didn't read the whole chatlog to be honest).
IF he thinks his account is worth more than 0.2, he might pay you just to get his account cleared. Otherwise, it'll be very hard for you to do something about this.
