GH Spammer is a advanced spamming tool. It can bypass any spamming filter, mails directly delivered to victim's priority inbox (In case of gmail), It can mail html content, can be used to spam multiple email id's.
This tool is developed basically by keeping gmail spamming filters in mind. (Viz. Spam filter, priority inbox, eyc..)
I designed it long back for one of my friend's specific needs. But now i thought i should share it with everybody.
