I know what you mean.
Sadly, I ignore all comments.
I was also wondering if there is an easier way to trash them.
My controls only allow me to select 20 comments at a time.
(I also use a wp-spam plugin that catches most of them – as well as requiring the complete lists of comment options before wp will accept them).
(there are also a lot of auto-approve blogs out there, so some do get through)
Right or wrong??
