It is really hard to detect scammed bounty campaign. After completing all the requirements to be able to get accepted in a bounty campaign, spending much time to participate in forums and not to mention carrying their banners, completing all the tasks and reports then all of a sudden you will just find out that you have been scammed already. luckily I am not the only one but to think all participants did the same efforts as well as you did. But it is really happening, lesson learned and could be just charge it to experience and move on. If we could only find out at early stage if we were in to scam or a legit bounty campaign. Who would really know anyway?
Yes, fraud is now very difficult to distinguish. I believe that it should take some time, and people will start to forget about participating in the ICO, because they get tired of running into any slag and not earning, but only losing their time. Therefore, if the market does not begin to appear really worthwhile projects, we will soon be without a bounty campaign.
