There is a PSA Announcement at /r/Steam that reads:

As ya’ll likely know, we’ve been dark to support the blackout against reddit’s antagonistic behavior towards its own userbase.

The admins sent us a message today saying we must open or get removed, so here we are.

For those of you browsing this subreddit on non-official apps (Reddit is Fun, Apollo, Sync, Boost, etc), they will break on July 1st due to reddit’s new policies.

We’re opening back up but will leave permanent stickies in the subreddit and threads to keep folks in the know.

Our Discord server is active, don’t forget to check it out.

Good luck and god speed.
