Admins, time to close the group registration. It's one thing to get
occasional mail-spam but I don't want to have to think twice about
clicking on links in the group content.
Go to group settings -> access, and set "Who can join" to "People can
request an invitation to join". Send out a mail saying that if you
don't respond in a human, python-interested fashion by 2 weeks, then
your account's membership in the group will be deleted. People who
don't reply by two weeks can always re-request authorization later if
they find they still want to contribute content.
This won't prevent people from seeing / searching the content in the
group (which is good), but it will prevent bad guys from adding bad
content to the group.
Please make it happen. If you don't have the time then I volunteer to
be the janitor and take the trash out.
