you will come to see that the fud is irrelevant and bogus once you check
https://github.com/SDCDev/shadowcoin
and see that it is one of the few coins (probably 8-10) with a clean and transparent commit history
you can follow back from shadowcoin -> blackcoin -> novacoin -> ppcoin -> bitcoin

I will not talk about any of the coins who's follower try to fud shadowcoin here
since they don't even deserve to be mentioned

Do your homework and check git repositories and commit histories

If you like to talk about shadowcoin I recommend the irc or www.shadowhangout.com
