The froum is not responsible for bounties and the forums purpose is not to conduct bounties but to manage a crypto community here. Most of the new memebers do not understand this , they mostlt think of this place as money making machine. But it is not. Bounty is secondary function here.
And on top of it, they create alternate accounts to maximize the money that they can take from campaigns, but in this process they forget a very thin line that differentiates between spamming and constructive posting limits and cross it and then they get banned and they break more rules by creating new accounts. My opinion has always been to stick with one account, do good on the forum, help others and and become an established member and after some time the money will follow you, but others want to earn money first and always try to take from the community in return for nothing, you should always try to give back to community as well.
Some of the legit projects already have similar things like that. They hold bounty with a high reputation bounty manager and pay all the fees, funds to him just like it was in escrow. In the end, it's really up to each project if they want to do a serious business or not.
Keeping money in an escrow wallet doesn't guarantee that the project will succeed in the future, if a project is good it can be a huge success even without any escrow in place for bounty payments as well, or if a project just want to scam people then they can do the same even with a fake escrow in place.
