Thus just like i already said, 75% or more fonts you pay for are so close to identical it would take minutes of staring at them like an idiot to perhaps* notice a difference. Lastly i would make some extremely subtle changes to each character, and WALA! That font is no longer the font i download, as it been altered. In the case where i could ONLY use a font that was a pay-font, i'd first download it for free, Next i would open that font in 'FontLab Studio' which i would also 'buy'. I'll use whatever font i think looks good. even if i tried to force myself, care any less about copyrights.
