# This evil script inserts junk data to flood gnunet. Seriously,
# it creates random content that can be fetched by other people
# to test the network. The idea is to provide fresh test content 
# each day and yet so that it can be found easily with a key
# that is relatively unique yet deterministic:
#
# Key: randtest-DAY.MONTH.YEAR
#
# It is left to the gnunet itself to a) make sure approach
# like this can't be used to harm the network b) the inserted
# random blocks disappear from the data caches in reasonable time.
#
# You can run this script daily from e.g. crond. Note that this only
# pollutes your own nodecache if no-one requests the inserted data.
