Texhnically pain is just a signal sent to your brain. Now does that make being stabbed repeatedly by a boxcutter any more pleasant? Technically anything made out of plastic can't be patented because you didn't invent plastic.
If any of those technicallys mattered do you know what people could get away with? According to graals rules apparentally it's rules over power any copyright laws because it claims to own any image uploaded regardless who the submitter is. Meaning according to the rules copyrights can be over ruled by the graal rules.
Seriously, that stuff is crap, take it with a grain of salt. Just because its uploaded doesn't mean its okay to take it.
