How often are you scammed for bounty rewards? It's no surprise some devs are scamming the bounty hunters to save costs. It's always upsetting to do a good work and finally this time is wasted if the devs don't send tokens. Scam means if you don't receive tokens at all according to the initial rules when you joined.
How often were you scammed in the past considered in percent of all campaigns? How many were paid? And do you have an idea to avoid it?
Hmm... In the past I have worked for 4 bounty campaigns. Of this, only one campaign paid me the tokens for my work (Traxia signature bounty). Two (Token Union and Magnus Collective) turned out to be scams. And I am still waiting for tokens from the last one (Blackbox foundation). So from my experience, I would say that 25% of the campaigns actually paid.
