>God Tier
Smaller, fringe communities stemming from old clans in games that no longer are played such as Wc3, WoW Vanilla etc. The game is no longer played but all the old players still get together and talk, either in chatrooms, skype-groups or old forums. Usually a very limited amount of members and impossible for newfags and underage to get into. Not connected to the outside world.

>Great tier
Smaller forums, clans, chatgroups etc for niche games or interests. Possible to get into as a new person but you really need to be interested in the topic. Strong defence towards attentionwhores and most underage. Filled with autists.

>Average Tier
More "unknown" places that yet are easy to access for everybody. 8ch, some smaller 4chan boards, slower forums, krautchan/int/, a few subreddits

>Bad Tier
Reddit, 4chan, bodybuilding forums, tumblr and other mainstream sites for everyone who can operate a computer

>Shit tier
The worst 4chan boards such as /r9k/, /pol/, /b/, /v/ filled with underage and newfags. Normalfag sites such as facebook, 9gag and twitter.
