I usually run whois without the '-B' - realise stuff is filtered - then
re-run with '-B'. Unless, as Frank asks, there is some form of rate
limiting - then  there is probably little point in filtering. It would
be cute that if the request is from an IP address associated to the
results, that any form of rate limiting is ignored - if there is rate
limiting.

For example, like this:

no security (because the query can simply be repeated with the “-B”
option), and reduces the usefulness.
