[FidoNet]
An infinite stream of duplicated, near-identical messages on a
FidoNet echo, the only difference being unique or mangled
identification information applied by a faulty or incorrectly
configured system or network gateway, thus rendering dup killers ineffective. If such a d
reaches a system through which it has already passed (with the
original identification information), all systems passed on the way
back to that system are said to be involved in a dup loop.
