Looks like this may be a bit of a theme for this guy...
Apart from Debian, he has also targeted Free Software Foundation Europe (FSFE) and it has got so bad, they have had to reach the extreme of pursuing legal action against him. He violated EU data protection laws by illegally copying subscriber information from FSFE's mailing lists and subscribed everyone to his own list. He also ran a script that tried to unsubscribe everyone from FSFE's lists. Then he claimed that what he did must have been legal because he has not been arrested yet, while at the same time continuing to use his list to spread lies and defamatory statements about volunteers and the FSFE itself. Which is something he has also been doing to Open Labs, accusing them of human trafficking, running a paedophilia ring, and god knows what else.
