do you ever follow the work bounty signature program, social media campaign but ended a scam?
On my experience, so far I haven't fall into those projects that turned out to a scam.
then how can we know the project ended a scam or a professional? Give me more tips
You said about bounties then before joining any of them make sure that you know who's the one managing it. See if there's someone that is trustworthy managing those projects but if it is just someone that isn't popular, don't have any trace of deal or history of transaction think again. Professional projects will hire professional marketing specialists or campaign manager to run their project to ensure that they are legit and paying.
