I kind of see it as the same argument as the sampling argument in music.
in all honesty im kinda over it, next time i run into that ill just leave comments saying "oh wow, you used my gif im so honored."
i kicked some rocks and did some reading about art and copyright laws to the point that i now feel it was to small of a battle to spend time on.
Thanks for your comments and input, ill start looking into watermarks and stuff but honstly i prolly wont put one, i hate the way they look.
have a wonderful evening/day!
:D
