I know that this is partially subjective, but try to share some webhosting providers with the ugliest templates.
Important: This thread is not meant to be an all-round bashing, please try to be constructive in your criticism and maybe shortly explain why you don't like the theme. I believe this can be very important feedback for hosting providers and should be taken a such. Nothing personal.
I start :-)
http://datasoft.ws/ Very ugly logo, overall too big font size, unclear structure - overall looks very cheap to me.

Your turn!
