Every post on Hive is an advert in some senses - an advert for your thoughts and ideas. It costs a minimum of $10 to make a proposal and I imagine that accounts will be hit hard by downvotes if they try to promote DHF proposals that are spam.
The lack of accountability for DHF proposals is a huge problem, yes. I attempted to introduce discussion of that into the Strategizer proposal, in order to improve Hive's profile to potential investors, who typically want transparency. Overall, this idea was rejected by Hive's stakeholders for their own, unspecified, reasons.
Yes, there is a lot of noise on X and in the notifications. It's important for there to be a better level of communication on Hive regarding DHF proposals in order to ensure that potential proposers of DHF work know that they are reaching the community and to prevent conflicts of opinion about notifications. There is no obviously 100% perfect solution, but DHF notifications might be one that works well. There is no way to know without experimenting.
the dhf notification really scare me a bit, could be so easy to abuse just create an a dhf to promote some random shit and expose it, could be an easy way to do physing or thing like that
it would cost a minimum of $10hbd to do that, but you are right that there are some potential issues. that being said, there are only a very small number of proposals being created - so it isn't difficult for them to be monitored for abuse.
