"/otter/" implies an anonymous imageboard. Not sure if the admin of otterchat will keep those two traits after revamping the site.
- if it doesn't, it fits just as badly as a runescape discord or your mom's facebook group.
- if it does, I see no problem with allowing /otter/, regardless of whether otterchat is part of the webring and regardless of whether the admin supports the team. Even if the admin is the >normies get out reee type, there are otters (heh) who want to manage the icup team. And everyone could use a bit of cross-pollination across these absolute niches.
