I personally feel participating in a campaign is by choice and not by force, in as much as I would have want an escrow but we should know that we cannot impose this on any campaign manager, so I think the best thing to do is to avoid most of these campaigns, if ko one is taking part then they will have a re-think.
agree because we can't force the team projects to escrow the tokens, but most important thing is to avoid the bm that not pay (by historycally), or if the projects was good, we can ask the team for the clarification
