It is very hard to deter people from spaming as they are hoping to get backlinks, and this is usually done automatically via a program.
You can stop comments altogether by not allowing comments, via the 'quick edit' menu for each post.
I do this as I found that very few comments were of any benefit to me.
If you get a large amount of comments, you can delete them all quickly, by using a plugin,
I think it is called 'bulk delete' or 'mass delete'. Do a search and you will find it.
On some of my sites with the comment enabled, if I only visit once a week, I can find 4000-5000 comments waiting for approval, so this plugin is very useful.
