A while back, there were three wars that all happened around the same time. There was so much tension and stuff that it all got mixed up into one big War.
There was the IR and SA war. Essentially, the Infinity Ring forum was a bunch of tight, close-knit friends. They stuck with each other, and, since the seies stopped having new books, there weren't very many new IR MBers. Tll one day, a whole bunch of SA MBers came and decided to attempt to... liven up the IR MB a bit. On the face of it, an honorable cause. Going deeper... wel.. One thing you have to realize is that the average age on SA and IR was pretty different. The IR MBers were a lot older than the SA MBers. So when the SA MBers started posting... they seemed immature to the IR MBers. This led to conflict between them, escalating until it turned into a full-fledged wat between IR and SA, with SA spamming IR's forums and a lot of all other things.
At the same time, tension was brewing here on T39C. New users were rising against the old ones, and the old ones rose up to meet them in battle. The old users didn't like some of the things the new users (I don't remember the specifics), and vice versa. There was an uneasy tension for a bit, until finally, between two specific users, things exploded. Over the course of a Saturday, people chose sides, armies were assembled, arrows were fired, and battle went on. This resulted in a whole lot of people getting permanently banned (mostly oldies).
Also at roughly the same time, T39C and SA had their differences. This was mostly sparked by the IR/SA war, since a lot of IR users were also T39C users. This was small in contrast to the above two, though.
This all happened in a few months.
And that is the story of how all my friend were banned and the MB started to lose some its activity :/
