You're referring to a very old post, it's better to do this since you'll likely end up making spam. That aside, are you referring to bounty campaigns? I think this is the first time I heard about "boundary campaign" even though the context seems to suggest you're referring to bounty campaigns in the altcoin section. Most bounty campaign pays in altcoin, rarely in stablecoin or Bitcoin. You're better off looking at the services board or participating in contests if you want to get a chance to win something and get Bitcoin.
