Wikipedia seems to suggest that Spamhaus blocked a large chunck of Cyberbunkers IP allocation, when the problem originated with a subset. I suppose given the conditions, Wikipedia is perhaps not to be trusted, but it does make me think less of Spamhaus. In October, 2011, Spamhaus identified CyberBunker as providing hosting for spammers and contacted their upstream provider, A2B, demanding service be cancelled. A2B initially refused, blocking only a single IP address linked to spamming. Spamhaus retaliated by blacklisting all of A2B address space. A2B capitulated, dropping CyberBunker, but then filed complaints with the Dutch police against Spamhaus for extortion. https://en.wikipedia.org/wiki/CyberBunker https://en.wikipedia.org/wiki/CyberBunker
