Take note that for both types of broadcasting, mechanisms are in place to punish
misbehaving peers who take up bandwidth and computing resources by sending false
information. If a peer gets a banscore above the `-banscore=<n>` threshold, he
will be banned for the number of seconds defined by `-bantime=<n>`, which is
86,400 by default (24 hours).
