233    - GISP has a obvious exploit, if a hostile peer is able to behave like "dumb"
234      peer. More specifically, a hostile peer answers to "SEEN" messages in the
235      network, but no dot perform requested operations, e.g., do not provide
236      a "RESULT" message for a "QUERY" message. This behaviour allows other peers
237      to maintain hostile peers in their routing tables while still hostile
238      peers are able to cause problems to the network's operation. "SEEN", "RESULT"
239      and "QUERY" messages are part of GISP-3.4 specification. Also,
240      a hostile peer is able to use this "dumb" behaviour with other GISP-3.4
241      messages.
