There's up- and downvoting and we use that to rate-limit comments that are being displayed as you go. Downvoted comments (like spoilers) get filtered out quickly, upvoted (or new) comments make it through the rate-limit. We're using a modified version of reddit's published scoring system.

Syncing is the single biggest technical issue and currently not easy since most platforms don't allow access to the point where we could really time-sync. Still looking at a few options, though.
