In last year's june/july there was some dispute about the Class::DBI module.
See schwern's journal entry, the Class::DBI::Frozen::301 module by sri, this blog entry (»Will Class::DBI fork?«), and the Acme::Class::DBI::NoThreats module (neither on CPAN nor BackPAN).
There was also some legal discussion about participation on mailing lists, like this one (from the old Class::DBI mailinglist):
*** was told he was temporarily banned from the list. He proceeded to re-subscribe anyway. In the UK, that is indeed a criminal offence. I've invited him to comment on this, but if he does not do so, I shall have little option but to proceed with reporting this matter to the Police.
Unfortunately most of these things were deleted from the web (modules, list archives, blog entries etc.)
