Links are not dead and the hosts you're suggesting are garbage.
RS limits free users to 50kB/s, one of the lowest limits around. They're even being sneaky about it by sending data in bursts of just providing stable speed - so people with slow connections get punished even more.
MF deletes accounts and files left and right, not to mention their 50GB space limit for each account and 200MB filesize limit.
Seriously, it can't get much worse than those two.
