Need a PHP bot created

Need a PHP Bot that would automatically post reply every half and hour a(customizable) to a specific threads of various adult forums(can be many)

Bot will first login to the forum. Then post a reply (which we supply) with gap of some time which we supply to a thread. Bot should deal with all the cookie and other stuffs which might cause problem.And this bot should work with VPN.

Bot should be able to post multiple replies without any problems. Account should not get banned.

Account should not get banned.
if you send automated replies to any thread of any forum..its obvious that the moderators will find it as spam..its not because they can see its posted by a bot..but its simple commonsense that no man can login and post similar replies every 30 mins for straight 24 hours

Still Send me details please..
Does it involves captcha?

i will see what can be done.
Thanks

Oh I am sorry if there was confusion the sites will vary as well as the replies

If risefromdeath does not take this, just send me a PM or contact me on MSN/Skype/AIM.
