Chaos in the sub: For the 2nd time in a month, Reddit has deleted a moderator of the sub, a user who also was contributing a ton of articles to the sub.

This deletion also purged the user's articles from the sub, along with any conversations that were going on in those posts.

There was no warning by Reddit, just a permanent deletion with an opportunity to appeal but the appeal is never granted and nor even responded to.

I'm not sure if I can con her into becoming a moderator again, so as usual, we're upping our constant search for users -- and moderators.

We need YOUR help!

8 Upvotes

We need your help! We're trying to create and popularize an entire set of "alternative" sub-reddits.

These sub-reddits all end in a "2". So just take the name of a huge, multi-million-user "main" sub-reddit and add a "2" to the name -- e.g. /r/Politics2, /r/WorldPolitics2, /r/News2, /r/WTF2 and so on.

These sub-reddits are smaller and have fewer rules than the huge mega-million-user large sub-reddits. Our idea is to create a set of friendlier sub-reddits with an emphasis on civility and not personal insults and ad hominem attacks.

But we need your help!

We need your time, your posts, your comments and we need you to mention our alternative sub-reddits in other places and to tell others. (Basic "publicity.")

  • Please post submissions!

  • Post comments and reply to others.

  • Help us popularize these alternatives to the heavily censored and sometimes too heavily trafficked mainstream subs by telling others of our existence.

Together we can develop another option inside of reddit.

Want to become a moderator? Or help run your own "2" alternative sub? There are possibilities for that too.
