Thanks for sharing the message, @sunshineblaze. That's very kind of you.
Just sent them a message:
Hi there,
I'm the lead developer of the WordPress Popular Posts plugin. Today, a couple of users have reported that GoDaddy blacklisted it for "causing severe issues with either security or performance". Since it's of my interest to provide a solution that works everywhere and for everyone, I'm writing back to ask you guys about the exact details that led to have WPP banned from your service. Hope we can work together to solve this situation as soon as possible.
According to the e-mail I got from GoDaddy, I should expect a response from then within the next 72 hours.
