A tool that harvests the ids of online users and automatically send them PM every 1 minute for as long as you want! (of course until you get banned). This might not be sounding a lot. But -> Some vbulletin forums allow you to send 1 pm to 5 people. Make 5 accounts on the forum, enter info into the tool, draft your message, let it run for 20 minutes! Do the math 20 * 5 * 5 = 500 your message sent to 500 online users as PM. And you know that people have a higher tendency to check pm than email, also no spam boxes . So just wondering, how much will you pay /month for a tool like this? Regards!
