I met with some instances when some other person using my credentials working for an ICO telegram. I only came to know about that cheater when I also applied for the same ICO telegram and reported to the bounty manager.
today I also found some cheater who has applied for twitter campaign using my btc profile.
link for the complaint I am providing below

I thought that most of bounties need you to pass a verification before you are able to participate. If manager does not care about fakes and do not check profiles, I would recomend you to avoid participating such event. It would be better to look for more reliable project.
