Apart from the normal website platforms that offers bounty campaigns, can anyone share a spreadsheet that contains list of bounties if there is any in a spreadsheet form. it could help from going to the normal altcoin threads searching for bounties.
You want a list of newest bounties, right? So I highly recommend you visit
http://bountylord.com/ They have what you want, even their rating for the project. Or you can click "notify" on Bounties Board, it'll send every new bounty to your registered email on bitcointalk.
