R/feedthebeast

/r/feedthebeast (https://www.reddit.com/r/feedthebeast/) is a Reddit subreddit for the Feed The Beast (FTB) and modded Minecraft community. It was created to focus on FTB in particular, but it currently focuses on modded Minecraft in general.

Associated subreddits
Wanting /r/feedthebeast to focus on discussion of mods without being bombarded with server advertisements and users reporting crashes, the moderators of /r/feedthebeast made two new subreddits: /r/feedthebeastservers, for advertising modded servers, and /r/FeedTheBeastCrashes, for getting help with crashes. Other associated subreddits include /r/TestPackPleaseIgnore for Test Pack Please Ignore and /r/AlienMC for AlienMC, although both are inactive.

Test Pack Please Ignore
Test Pack Please Ignore was created by and for the /r/feedthebeast community as a GregTech 4-focused modpack and hosted on Feed The Beast (FTB) and Technic for Minecraft 1.6.4. Test Pack Please Ignore 2 was created as a sequel to it just on the FTB Launcher for Minecraft 1.7.10. It was planned to be released on Technic once it went out of beta, but it never did. A Test Pack Please Ignore 3 was planned, but nothing came of it.

AlienMC
AlienMC was a server also created by and for the /r/feedthebeast community for Minecraft 1.7.10. The original server used the Test Pack Please Ignore modpack, but it later restarted and used a custom AlienMC modpack. The server ended up being severed from the community and was rebranded as "Black Sun Network". A new modpack and server called Black Sun was created for Minecraft 1.10, but the server went down and the modpack has been abandon.

"Best of" awards
At the end of every year starting in 2015, the user of /r/feedthebeast vote for the best submission of the year, the best comment of the year, the best build of the year, the best new mod of the year and the best new modpack of the year. The winners get two months of Reddit gold and a special lime green flair.

Modded Minecraft Discord
/r/feedthebeast has an official Discord called the Modded Minecraft Discord. It is moderated by the subreddit's moderators, plus volunteer "police." It is one of the largest modded Discords, with over 5500 members, behind the Technic Discord with 30,000 members. It has a list of other modded Discords in its #mod-guilds channel. The Discord is officially partnered.

/r/place
In order to participate in Reddit's April Fools experiment, /r/place, the /r/feedthebeast community created a blue box with a the characters "r/ftb," Clay and a Dragon Heart under it, near a flag created by /r/ireland.
