As I wrote about 4 times in the mldonkeyworld english forum:
This is a problem of ALL ed2k-net Clients. Corrupted blocks are a 
problem of edonkey, Hybrid, lmule, emule, jmule, cdonkey and mldonkey. 
(at least 5 of them I personally tried ;) )

It seems that some smartasses want to get credit by uploading fake 
chunks to other clients, so they upload a lot of "zeros" (they get well 
compressed by emule). It "could" be an action of some other organisation 
(overpeer), but there seems to be at least some evidence, that it is a 
emule-mod trying to get credits (the real stupid thing is, that the 
credits are not granted, because the real uploaded data and NOT the 
uncompressed data is taken in account...)
So if you get some zeros, your whole chunk is bad, and has to be 
redownloaded. There are a leats 3 different patches for emule, that try 
to identify the "zeros-uploader" and ban them. At least 1 emule-mod is 
already been released, that will ban these fakers...
