And this is the flaw of decentralized platform,
The solution?
Nah, Even me don't know the exact solution, for it has always a flaw in the system this kind of person wanted to take advantage.
Only flagging is the best solution for this, and also if the seemit inc will step in and flag it also, but will they care?
I think they will not as long as they as the investor who buy large amount os SP to do such manner and it's fine to them!
