The only way to combat bots is with other bots - made by people who care about the problem. Program sniffers to detect repost bots and flag them, and other bots to ban them.

It will be a constant arms race to keep up with them, but it’s either that or let them overrun everything.

It’s also on the users to pay attention and when someone calls out a reporter to take it seriously, downvote and report them. The most annoying thing is the number of people who respond “who cares if it’s a repost bot?” They don’t understand that such bots left unchecked will consume everything, leaving nothing fresh behind, because that is their nature.
