nah... It's not very hard to register and guest coment is perfect for trooling (use it+anonymous proxy like tor and you can flood at will).
Oh, yeah, based on the level of comments about vgchartz in other foruns, what you must do is to get a firewall with DDOS protection... I don't like when sites that I use to enter goes offline and there is A LOT of plp blamming vgchartz because they "are BS" and "it's vgchartz fault that NPD...", if someone out there uses a botnet...
guest post will be a perfect tool for those vgchartz-haters to flood like Indian tsunamis...
