I also had the experience of joining a project campaign to promote it, but after the bounty was over and within a while they disappeared without telling everyone, from there I started to be careful in looking for projects to join the project in the campaign.
That means if the project is only wanna getting the free promotion. I have been seeing a bunch of the scam project like that. Some scam projects were even changing their contract to the new address to make the tokens that distributed to the hunters became useless but their tokens were dead too.
I guess there are so many hunters have experienced this and almost all of the hunters ever promoted the scam projects. I have wasted a few months to promote the scam one called kittiefight.
It's a difficult time for us when the project became another scam.
The worse one is none of that, the worse one is literally asking money and I can't believe that. When a scam project says that they are giving away this many tokens, and says that they need 0.05 ethereum for the transaction costs, that project is a scam project and they are not after giving you any money at all, no real project would ever do something like that. First of all they can send you their own token for nearly free, that is aside, if it costs a lot, they should be able to pay that much, because you are working for them and you deserve it.
So long story short all the ones that asks people to pay them some money for "transaction costs" or basically any reason at all are all scams. Those are the worse ones in the market right now, taking money from people who do not know how it works, and they even list their tokens price made up so people would assume it will be like that, whereas nobody agrees to that.
