Incorrect. I would not say the figure is as high as 75%, although I do think it's the slight majority (i.e. 51%) that may do. It's a shame really, due to people's pure ignorance and arrogance.
Nevertheless, even if (or when) it gets to the point that 99% of the IRC population is using it to file trade, we'll not help with breaking the law as long as this forum or mIRC exists.
