We're not going to get into a law debate, laws differ from country to country, blah blah blah, it's all been said before. The point it comes down to in the end, is mIRC isn't a file trading program - it doesn't matter a) How many people use it for that purpose, b) The fact that the DCC protocol is supported by mIRC or anything else. It's just a plain fact. Whew.
The other point of course is, we have policies on this forum - very few compared to many sites, but there are some, and as 90% of the general users and regular users that come here manage to keep in line with the rules, so can you and the other 10% of people that find that because they disagree with something, gives them an excuse to do what they want.
The person has been answered, this isn't gonna go into an argument
