Have I been hacked?

Take a look at these pics and tell me if I have been hacked..

This started all of the sudden and I took these pics about 5

minutes into the situation… about 45 signups took place in

this time frame…

The first pic is a picture of the whos online plugin I have installed.

new blogs are simular…
