I understand that point of view, but - as a being a downloader myself as well - I am quite unhappy about the rough restrictions at k2s & fj, as you only get about 50kbps or less as a non-premium-user. As there is no share-online anymore, I prefer multihosters like Deepbrid, iDebrid, Premiumize, etc. With cheap accounts I can get fast access to ~50 differents hosters, but k2s & fj are blocked anyway. So, for myself, I don't see them as a alternative as different sites prefer different hosters. I'd think about Rapidgator, but they banned my VPN. No prob for downloads as they don't ban multihosters. Still I'm thinking about the right one for a premium acc,...I tried it again, first with uBlock Origin: no probs at all, 30s to wait and full speed dl. But with uBlock Origin turned off it tried to redirect me to other suspicious websites
So sure I'm with you and the ban. Maybe I choose filecandy, sendit.cloud or Your Cloud Box. All of them give at least 500kbps to free users and great conditions for uploaders as well. I'm looking into further experiences within the next week.
ZippyShare seems to be the best one for me at all if I could just pay them for turning off the days-to-delete-limit
