Someone did my job for me and submitted a bunch of dead board resports. I knew about some of them but usually let them linger for a bit in case they come back. Anyway.. these are gone:

WAPCHAN – 404 – this one is back.
Sidson.city – cloudflare time out
83channal – forwards to aggressive spam
Epitto – ssl error and switching to http does the same aggressive spam forwarding as 83channel
Finalchan – connection timeout
Christ-chan – connection timeout
Red Channel – Illegal content, site removed

Kind.moe – loads to a blank white page

Boards removed for being dead below. Never had so many 404 in such a short period.
As always, comment below if you know what happened to any of them or know if they moved etc..
