The instance list is fine as is. Think about it like this: do you want racists to join a single instance so they are all in one place? Or do you want them to spread across all different instances, causing moderation problems everywhere?

I want to be charitable here and assume this is in good faith, but I can't help but point out that this is almost one-for-one the containment board logic non-/pol/ 4channers used to justify the existence of /pol/.
