LOL, Red, I have seen that too. It's entertaining sometimes.
But, people have gotten mad at me for 'Koda' saying I stole it and blah blah blah. The common one was "I had it on IT!"....well so did I lol! But out of a few hundred people and limited designs and names, of course there are going to be similarities. >.> You dont see people getting mad in the real world... I know several other Michaels, but I don't go around calling them "name stealers" lol. Or character design stealers....LOL how does that work? Man... "You're the same markings as me! You're the same as me, or relatively close!" Who cares? Are they you? No. xD Just shove it in their faces!
It just happens. People can be bleh about it. Best thing to do I guess is ignore them and not start anything.
