A lot of projects are spamming bounties without paying or even answering

There is a lot of projects that are just flooding algora with spam, people solve the bounty and then they start ghosting.
I have solved a bounty for Dimagi and they didnt even tested my code and moved forward wasting my time without any punishment, and advertising their project for months using algora.
Also there is a lot of projects that only publish bounties for their own employees, meaning that nobody else can claim it or work on it without wasting his time.
I have been months trying to contact someone in algora and nobody ever answered an email or whatsapp, why not just close the web if its useless and full of AI coders trying to claim the little number of real bounties that exist, whithout any punishment?

Here is the bounty i solved without getting paid, and there is a lot of cases like mine in other projects....
https://github.com/dimagi/commcare-android/issues/2740

No Algora files, tests, or entry points are identified in the issue; the only referenced work is Dimagi's external issue #2740. First determine whether bounty verification, payment enforcement, project eligibility, or moderation is within this repository's scope. Done would require a specific, agreed change and clear acceptance criteria.
