This site automatically supports emotes from Twitch and FrankerFaceZ in various places (guides, forums etc), as well as some from BTTV and of course our own emotes (since it has never really been published, I've added a list of them at the bottom of the post).
As you can imagine, not all emote codes are that great so some of them can appear in normal text. To this end, we have a number of emotes that are blacklisted to prevent this.
For the most part Twitch emotes are not a problem, since subscriber emotes have a prefix anyway. However Twitch has recently added a bunch of subscriber emotes to their list that do not (yet) have prefixes, which caused them to show up everywhere. Trollbear666 has kindly gone through all the games pages and all/most of the problematic emotes are now blacklisted, but in case he missed some or if Twitch adds even more of these, please post them here or contact an admin so they can get blacklisted.

UPDATE: To circumvent issues as much as possible, FrankerFaceZ emotes now need to be prefixed with "ffz" to show up. eg. ZreknarF does not work, type ffzZreknarF to make it show up: ffzZreknarF
Also emotes will only show up if they are surrounded by either whitespace or nothing, so no more partial words turning into emotes.
