Reddit is as always a mixed experience.

I think any successful forum depends heavily on its mods (notably like this one) to maintain community and civility, to remove spam, abuse, brigading, and astroturfing. This works despite the corporation trying to monetize with both hands. Reddit still has some subs with good mod teams where kind, productive communities are carrying on. This could happen on any decent forum software.

And yeah the rest is commercialized filth.
