Using whois commercially

Hello all
I was going through post on forum where a user suggested that he needs
to extract information from querying different sites using whois .
To avoid his IP blacklisting by Whois server, he will provide a list
of IPs which can be used . I want to know if its possible or not .
Because most of the time ISP drops the packet if it does not belong to
their network and we can not develop commercial software which
depends on whois query according to my knowledge . Although i am not
networking expert but i gave a thought to it. My first though was
sending whois request from different ip address [ ip spoofing ] so
this way Whois server will not blacklist the ip but this way i will
not get the response. The response will be send to other IP. My other
thought was sending chunk of requests from different proxy servers and
getting response. Could some one please put some insights about this
if its possible to exploit the whois using these sort of things .

Commercial use of WHOIS data is usually not permitted. The moment you
are starting to think about how to circumvent IP blocks etc. you know
that you're going to do something which is either illegal or at least
not welcome. Therefore it WILL break sometime sooner or later.

JUST DON'T DO IT.

Jamma.

PS: Apart from that WHOIS data is often obsolete, incomplete or totally
bogus. It's getting near to useless these days.

Thank you for your reply. Actually i am not going to do it. I just
wanted to know how it is possible as i got two methods which already
failed. First one IP spoofing and second one proxy server . I just got
curious nothing else .
