Digg may have a bot problem but Reddit isn't far behind. So many subreddits are full of slop that they've become useless and/ or completely unreliable.

What's an actual viable solution to this kind of thing?

CATPCHAs aren't it. Maybe micro-fees to actually post things would discourage bot posting? I really don't know.

Seems like it's just dead internet all over the place these days.
