Have you checked if there are open issues for any of these sites?

Another one that should be removed is hitbox, which has been dead since 2020.

@LoneFox78 Thanks for the hint.
Discovered a mistake in my testing method, where network errors would cause a skip, which meant the test was counted as a pass. Re-ran all tests and found these additional dead sites:

• clipsyndicate (Site redirects to some 2-year-old landing page. Looking on IA seems to have been down since 2021)
• fusion (Dead since 2021)
• hitbox (Dead since 2020)
• mnet (Moved to mnetplus.world and TVING. IDs are different)
• watchbox (Dead since 2019)
