This is a good idea of space, but I do not see the project being interested in advertising the social community. Bounty bonuses are not attractive, I think if you need improvement then the community will be more interested.
They don't do an ICO, so a usual bounty campaign wouldn't make much sense. I guess they use other kind of marketing which will benefit their project more.
Actually, they have a bounty campaign but not a lucrative one.
Offering very little amounts of token.
Nowadys it doesn't look the best way of promoting a project so I can understand their reasons for not doing a big one.
