Few small general suggestions compatible with all userscript managers

@match performs better

// @include      http://boards.4chan.org/*
// @include      https://boards.4chan.org/*

Performs better as:

// @match        *://boards.4chan.org/*

Therefore ...

// @match        *://boards.4chan.org/*
// @match        *://sys.4chan.org/*
// @match        *://www.4chan.org/*

Having @connect * makes all other entries irrelevant. Furthermore, with @connect * (supported by TM) it means everything, which is the same as not having it at all.
