in theory, you can exclude anything that is a text post, but a lot of the content posted on sum subs that you want are self posts. like sports post games, weekly resets in games, or transcripts of twitter threads.
It became a problem because it meant they were forced to bow down to advertisers instead of leaning into user funding. Discord has leaned into user funding very heavily, but I don’t know of any other social media that is more funded by its users than it is by ads and is regularly used/promoted, at least in the US.
Does it let you use it on specific users? Some bots would be useful to put it on. I know of a few that post relevant videos automatically or aggregate game API data that would be good to add to a few subs.
