Let's reverse the question:
Does all the ICO that was announced here in Bitcointalk forum were legit?
Absolutely,
NO. Same answer to your question.
Bitcointalk is a medium of communication/discussion, it doesn't guarantee that a project/ICO posted is legit. So, don't think beforehand that an ICO is a scam if it wasn't announced here, just do a thorough research
