I think my favorite 'mainstream" forum on Reddit was the /space forum. It's got a huge number of followers and a lot of active readers compared to any other forum. The moderating seems to pretty kick back. They appear to prefer to simply let the public vote topics up and down and allow the public input tools to decide which content gets priority and which content ge's buried. I guess that's only logical considering their size, but I was pleased to see that my posts weren't simply deleted by moderators based on their content even if they got buried by voters at times. All things considered I think it's probably my favorite mainstream forum.
The /astronomy forum on the other hand is *heavily* moderated and down right draconian. I got banned instantly from that forum awhile back simply for posting a link to a published paper by Peratt without the slightest warning either. Evidently the mods there are rather heavy handed and have a huge chip on their shoulder towards anything even remotely related to EU/PC models. Apparently even published papers are not welcome there if they support anything other than the LCDM model. It reminded me Cosmoquest. I suspect that they share a lot of the same moderators.
The /astrophysics forum is a much smaller community which seems to be moderated by younger mods with an odd sense of humor and little if any respect for conventional thinking. They seemed to have no problem with my posting of EU/PC oriented material or asking tough questions. I get the feeling they're just having fun at the expense of professional astronomers and they don't take anything too seriously. I actually enjoyed that forum.

/universe is even a smaller community than any of the rest ,and the moderators seem to have a chip on their shoulder for ideas that fall outside of the mainstream. I had a good conversation with one of the mods, but eventually he removed the entire thread because things didn't go his way and it deviated from their 'preferred' content. A least they didn't ban me outright however, so it's "better than' /astronomy in that sense. I wasn't personally attacked there either, but the moderator that I talked with used a lot of loaded language like "pseudoscience" when describing EU/PC content and he didn't seem to have much tolerance for open debate.
In terms of a preference for public voter moderation, the /physics forum is pretty kick back. Like the /space forum, and unlike the /universe forum, the moderators at /physics didn't seem interested in controlling the content themselves, rather they let the public voting tools control the priority of the content for the most part. None of my posts there were removed based on content.
Our EU/PC oriented forums are the best of course in my subjective opinion, but I was pleasantly surprised by the kick back moderation style of most of the mainstream physics and space oriented forums, with the exception of the /astronomy forum.
Anyway, those were my impressions of Reddit.
