I will (when I see or when I have time) leave a temporary tag if the manager clearly states that he does not guarantee payments. Also a mandatory tag for accounts of projects that themselves try to manage the Bounty (without depositing funds). I will also mark with a temporary tag managers or projects publishing false positive statements in the spirit of "the token is expected to cost $1", etc.
The manager gets a fee for the work. Right? So why should users be left without payment if the project does not pay the funds? I do not think it is normal for the manager to say something like "Sorry guys, the project team has disappeared and you are all left without payments"
This irresponsible practice should not exist in its current form. This kind of disclaimer is a fiction that is aimed only at getting a fee and covering their ass (so that they can continue to receive fees).
We can go the other way and stop this right now. A temporary red tag warning that there is no guarantee you will get paid.. Users received payments? Great! The red tag is removed (and of course the tag remains if payments were not made). I am ready to start if you support me. A few tags like this are enough to make any manager think twice before taking a fee from a dubious project in the future.
