Is there any rules on this forum to prevent this kind of fraudulent works because I see that most projects just use bitcointalk to promote their project through the hunters and then the hunters will not be paid at the end of the campaign even if their project is successful.
You've been a member of bitcointalk since 2017; don't you realize that Theymos doesn't give a shit whether bounty hunters get scammed or not? Have you not seen all of the scam accusation threads dealing with situations exactly like the one you described? It's not like this is the first (or even 10th) time this has happened.
As to the second part of your statement above, all I have to say is "duh". That's exactly what a lot of projects do, and it's the biggest problem with bounties that promise to pay their participants in worthless tokens once all the spamming is done. They have no obligation to do so, even if you think they do. They can't be forced to pay and they'll easily just skip right past that part once the project fails or if the project owners get greedy.
My advice to you is to smarten up and stop spamming for these lousy projects that only want to make money for themselves. They don't care one whit about you or any bounty hunters. Bounty hunters are just a desperate pool of suckers they use as a marketing tool.
Sorry if I'm not fond of reading especially in this thread. I only read and get information through the complaints of most bounty hunters in the telegram group. And this is my first time posting this kind of issues about the fraudulent project.
Previously, I also encountered the same issue with the Amepay project but fortunately after a long period of waiting and complaints by hunters, they provide payments to all participants.
However, thanks for your advice, I really appreciate it.
