People don’t want to see uninteresting replies and casts.

Best way to solve for that is weight historical inbound engagement for a user, i.e. PageRank-like score for every user.

Disproportionally hurts new accounts. Making it harder to get started.

This is fundamentally caused by the lack of negative signal in the Twitter model.

Proposed the downvote button multiple times and people did not like the idea!

Downvotes would ruin the positive vibes, truth is the value of a reply is too subjective and people making honest attempts at engagement might be disheartened 

Allowing users to mark a reply as spam though might work as it should be clearer cut 

The occasional false negative would be a tolerable price to pay
