there was a service or two that did offer filtered feeds where traffic from
certain individuals and systems was certainly removed... it isn't the first
time such a feed has been offered in fidonet, either...

FWIW: the tool used for that feed was developed by someone in Z3 back in the
'90s where there was a huge problem of traffic from othernets (a pr0n network
in particular) was being injected into fidonet... the injections were taking
the headers from valid fidonet traffic and putting them on the message bodies
of the injected traffic... these pkts were then being dropped off on systems
that processed pkts from their inbound directories without validating the
sending system information in the pkt headers... this lead to more systems
implementing pkt level passwords and also the implementation of secure and
insecure inbounds...

those filters are a GoodThing too :)
