I think the best way is to incentivate community to report possible spam and if many people tag a post with possible spam that post and that account need to be shadow-banned or something like that. I literally create this account a few minutes ago because i want to try this social and i notice many post that are spam. And if i’m right this app is decentralized and no one have control. So if the community have a control the only way to mitigate spam is that.
