I have some mixed feelings about this one;
There's a few things:

Project related:
----------------
- Although the idea is good, the setup is terrible.
- Last giveaway had (as far as i know) 1 entry, and my honest thoughts are that it was probably someone involved with ganjaman ( Associate, friend etc ).
- There'd be no real way to prove, so if things like this keep being the giveaways then he could be stealing the funds generated from selling masternodes by 'pretending' to give it away.
- The choice of world issue that got picked for first reward was woeful, and also a prize for masternode, atleast one of the winner IS ON your team [art3m] ( WTF! )

Owner related:
----------------
 - Ganjaman doesn't to seem very professional with his responses at times. ( albeit responding to accusations can take its toll )
 - No Transparency - Should be showing where you hold the funds, show where they have been sent, and how winners have been picked and how many entries there where etc...

Whether you and or your project is legit or not, you should take more steps to answer questions from disgruntled investors ( without cheek/attitude/anger ),
You should have a clear / precise way to determine winners if chosen at random or by chance, and you shouldn't reward people on your team with prizes you are offering to the community.
( Pay out of your own pocket if you wish to reward the team that works with you ).

No hate on the project, hopefully you can refine the rough edges.
