WCCFFN

In the fandom of the webcomic Cyanide & Happiness, #WCCFFN is a phenomenon in which an influx of users with no understanding of an online community's norms talk mostly to hear themselves talk, briefly making participation more difficult for regulars. It is related to Eternal September.

Whenever a large number of users are invited to a public chat, forum, or comment section, there's a short period when people join and talk just to talk, until they get bored and become inactive. In the late 1980s and early 1990s, for example, the Usenet forum platform was dominated by universities. Every September, at the start of the U.S. school season, a large number of freshmen would join Usenet, and it would take a while for them to learn the community's norms. But in September 2013, AOL bridged its own forum platform to Usenet, leading some critics to call the era of commercial Internet a "September that never ended," and even to refer to dates by the number of days since August 31, 1993, as if the current month and year were still September 1993.

In October 2015, the comment section of Explosm.net (publisher of C&H) left beta around the publication of comic #4080. Half the comments on each comic were to the effect "We can comment for free now!" as participating in the beta had been a perk of being a paying patron. This eventually contracted to "#WCCFFN", as if it were a hashtag on the Twitter microblog service. The "yellers" eventually got bored and quieted down, leaving those people who were actually writing something reasonably thoughtful to form a community.

Years later, Explosm started a chat community for C&H fans as a server on the Discord chat platform. Once it left beta in April 2019, it saw a similar influx of people who would just spam emoji or the lyrics of the Minecraft filk [https://genius.com/Captainsparklez-revenge-lyrics "Revenge" by CaptainSparklez feat. TryHardNinja]. This made it difficult for more thoughtful users to keep up with discussion. Some of the more thoughtful people without the time to look past all the copypasta memes lay low until the "yellers" got bored and returned later. Others left for good, not knowing from experience that many of these September-like events end. The situation repeated itself months later when Explosm mentioned the server on the Facebook page for C&H.

the yellers to yell and keep yelling, especially if moderators don't establish minimum standards. Some claim this happened circa 2018.
