Carsen is not a scammer.  But do you know who are scammers?
The coders that copy Carsen's free code/ideas and implement those code/ideas in other cryptocurrencies  w/o giving Carsen or Denarius any credit.
When a coder copies code and adapts it, they should still credit the source.
It has happened multiple times in the past.  And I am sure will most likely happen again in the future.  

PS:  My hat is off to those that have given Carsen credit in the past for copying his code.

Imitation is the sincerest form of flattery Carsen.
