First of all - thank you for this topic and for this one "Guidelines, how to spot a scam ICO & report effectively" - they are really very useful.
I'm also a bounty hunter who follows many of these rules before join the project's bounty campaign and now I'm trying to create a source where I can share these campaigns which are likely not a scam.
I like to discuss them with some experienced bounty hunters in Telegram before publish them here - https://bountygalaxy.com so I invite all of you to have a look at my website, you can be not agree with me but you can be sure that at least a had a look and not blindly add them.
PS Sorry for the design - I'm not a good web-designer
