I come across different posts and allegations that bounty hunters are dumpers and they make projects lose it value upon exchange listing. But from my experience with bounties most projects don't offer bounty allocation of more than 5% of the total token sold. So how will 5% dump have a huge effect on the remaining 95% price. And what about projects that don't have bounties but still dump hard on the exchange, is it bounty hunters too?
The bitter truth is that most projects dump because of the ridiculous number of bonuses the team have offered during the tokensale and pre-sale period. Imagine giving investors 70% bonus for their investments, they can decide to sell everything off and be happy with the 70% profit.
It is not the only reason why people blame ICO project. Let us say they listed the token and went dumped, the problem is why the token dumped? They don't have development and product at all. You said is favorable with developers who did not care about their investors. What happens to the investors who bought the token thrice the price they listed in exchange? Probably, they lost a lot.
In order to have a good feedback under ICO,, they should also protect their investors from loss.
