No idea what fumacrom is. K1 only uses adfly redirects.
Clicked the zerochan link, it links to zerochan.
Clicked the other links, it eventually linked to mega.
Your computer could have a redirect hijack, try running malwarebytes anti malware and adwcleaner.
Also try a DNS flush, some other site could have picked up K1's old IP which changes every 72hrs? Don't quote me on this one though.
