Reset won't suffer a downfall like GAF since its leadership is more decentralized. Evilore and NeoGAF were/are strongly linked. Anything that reflects badly on Evilore, reflects badly on NeoGAF and vice versa. That is partially why when Evilore's shower escapades came out, it hit the whole site. Rest will instead suffer a slow but steady decline as the community becomes more and strict on what discussions are allow and how you should express yourself.
Reset will chug along, slowly perma banning people like Nintex until it is left with its core audience. With no obvious wrong-think people left to ban, banning left leaning people not sufficiently "woke" will start to happen. Soon you will have a community where only the most "woke" are willing to post regularly, which will obviously dictate how discussions on the site will go. The site's insularity will shape its reputation as being a no fun zone where you go to laugh at ridiculous lefty hyperbole from ultra, morally righteous busybodies.
