I don't really know.
In my opinion, DHF should exist, but perhaps its use for projects should be controlled differently.
Auto voting and bots - I don't see anything wrong with that either (although it may be running in a slightly more convoluted way at the moment) - after all, it's a game and bots are part of that game... The money for this should come exclusively from private accounts.
Downvotes – I agree that they should exist, but again in a different way, not so that whales can deliberately destroy users they disagree with.
