Hey
No I didn't and to be honest I don't really know what Hellraiser is although I've heard of it before.
The reason I chose the name is actually kinda weird. When I was younger I used to play lego star wars with my siblings and there was a bounty hunter (IG-88) with an oddly thin head so me and my siblings used to call him Pinhead. I liked the name and I've been using it since.
Probably a lame reason for a name but it's a reason nonetheless.
