There are lots of total ****ing assholes who managed to get themselves
filtered in the groups that they most want to disrupt. If they want to
keep annoying that group they post to a number of groups. They count on
people in one group replying and not bothering to check for cross
posting. Then the idiocy they initially sent out gets included in the
reply and it goes out to all the cross posted groups. People in the
target group don't see the name of the OP in the header, so their posts
end up in that group.

My filtering for cross posted messages seems to be working fairly well.
It's not perfect, but it seems to get most of it.
