how you want to do that? you can not control the mass. Like @fiveboringgames said i think a bot to downvote spam posts is a good thing.
But if the mass come we aint seeing nothing yet. the mass is not a good writer nor blogger nor are they a astronaut with moon stories.
expect the worst and hope for the best
peace
If this masses come with the right atittude all will be fine :)
Good point hopefully by the time that happens we will have more filter options, or more specialised topics
