Your title says
I think, IOTA can be the biggest delusion ever (
not a scam of course 
)...
And then here you say
IOTA is a simple scam, not a P2P system.
What exactly is the point of this thread? Is it a scam accusation or just some other thread taking about weaknesses of a project?
If it's the later then i would suggest you would move this kind of thread to Altcoin discussion.
If you are to make a scam accusation in this board, then be straight to the point and not just beat around the bush.
