Yes, it is normal. You understand that when you join a campaign bounty, you agree with its rules. And with any changes to these rules at any given time. And the project has no obligations to you, since you are not an investor.
So, I received tokens, I managed to exchange them on the exchange - well. The project did not pay anything, or the token could not get on the exchange - forget it, and move on.
Don't judge bounty hunters also because all of campaign that can join in every ico you need to send reports time to time. Even you call this a free work you apply also in the sheet for beggining on it. It's also hard to find campaigns for people who get scammed and wasting time and effort on it. If they think don't want to price of their token get dump it's better also pay them Eth/Btc after working in a ico.
