now my questions is
why are they banning bounty hunters for promoting such project??
how did they think bounty hunters or bounty managers knows about the project if it's scam or not??
does bounty hunters or participants of such project requires to be ban or suspended??
So, you want to say that you got banned from Bitcointalk previously and now you're evading ban?
Now I will try to answer your questions with my thoughts:
1. Who are "they"? Bounty hunters aren't getting banned as long as they aren't breaking forum rules. Even if you promote scam project, you won't get banned. Red trust rating is worst what can happen.
2. It's their task to make reasearch about project before starting to promote it. Saying that you didn't know it's scam isn't excuse.
3. Nope, because scams aren't moderated here.
