Exactly what it says.

I have no idea what you have done to the website to make it this unbearable, but it is beyond impossible for your website to function properly when trying to draw from a mobile device.

Just what have you been doing?

If I want to draw together with people, I want to draw together with people, regardless of my choice of peripherals.

If the ads aren't causing the site to slow down to snail speed, then the complete lack of stability is mucking it up.

Why do you have to make everything so inconvenient for your users?

I'm experiencing the same issues on a regular desktop, too. This isn't just a mobile issue.
