Yeah I guess this is right, no one really could tell which one is the best campaign to joined with unless you try and put some efforts in it.  Many of us tried joining campaigns, some have succeeded  and some ended up in scams.  Too bad but it is what it is.  We just have to be more cautious in joining, be more resourceful, do some research first about the bounty project back ground and the member who initiated the campaign in the forum then put a dash of faith and good luck!
