The Brief: Copypasta is information that spreads online through copying and pasting.
Similar to chain letters and emails, copypasta is information that spreads from person to person through digital replication. Oftentimes, the information in a copypasta is not reliable and may be a part of a misinformation hoax or scam. Copypasta can also be a way in which stories are posted to different online forums. A genre called creepypasta is scary stories and spooky urban legends that are copied and pasted online.
R/Copypasta is a subreddit dedicated to archiving various copypastas from around the web.
