Best way to prevent getting caught sharing files illegally is to simply not do it. I have been told that there is a possiblity that these bots that are proposed to log the IP's of users will gain the information by tempting them to download files from them. The bot will then collect the time, date, nickname and IP address from the DCC session. The other thing is that the law, apparently, will only apply to the US as it is being introduced into their parliament. There's a big 'ahhhh okayyyyy' here because there would be nothing stopping affiliates of the RIAA around the world demanding that other governments enforce the same types of laws. Most IRC servers are either in Europe or the US so that is likely to be where the concentration of 'patrolling' will take place. Look out Quake and IRCnet users and possibly Kazaa.
