all posts that have max_accepted_payout set to 1 HBD are D.BUZZ posts, no matter on which frond-end the post was written
all posts that do not have max_accepted_payout` equal to 1 HBD are not a D.BUZZ post.
If you or someone else that is more connected in the HIVE community can get Hive.Blog and @peakd to implement this change, of setting the max payout for posts published to the DBuzz Community to $1, please make it happen.
It would still be a temporary and somewhat messy fix since DAPPs could still launch, even tiny ones that are bootstrapped as simple services to game the system.
I believe if you were us or another DAPP wanting to offer a reliable service without interruption from rogue actors, you'd be interested in code that made it impossible to game the max_accepted_payout as opposed to relying on verbal agreements with others, and the belief that everyone else in the future would agree to those agreements too.
