>>70283888It was a pretty old thing which dates back to the airing of the Railgun anime and the beginning of the Raildex general threads. Back then there was a massive amount of infighting between fans of the franchise as a whole and fans of the Railgun anime (mostly Saten). It went down to the level of what to call the threads, and lasted for over a year. It came down to Ingun, Raildex, and Toaru. Animesuki and other forums used Toaru, and that was immediately cast out because of that. This led to people spamming posts at the beginning of threads like
>Raildex>RailIs this a
newfag thing?
after Raildex became more widespread in use, coupled with Saru Lock shitposting. Then people sarcastically started calling the series Kamachiland, Shiageverse, and a host of other silly names. But Raildex stuck with /a/ as a whole to this day.
Put simply, Animesuki and other forums use Toaru, and they are people that /a/ does not want to associate with at all. So Raildex won out here.
sage for an incredibly shit thread
