I police comments pretty strictly and for this I give no apology. If your comment looks like spam and reads like spam it will be deleted. I have an open comment policy to enable legit people to comment but at this stage I'm deleting 5-8 comments per DAY. A few legit comments may have been deleted, but I doubt it.
I get an email for every comment, I try to deal with stray comments as soon as possible, feel free to email me if something slips through, my contact details are on the sidebar, or at least were last time I checked.
