Just setup the spamwords.dat file to have each word/string that you
want to reject for separated on each line.

Will you share your spamwords.dat file? I get too excited trying to
type them in myself. :-)
This reminds me (if I have my story correct) that recently a
Christian web site had a similar filter except it filtered news they
scrubbed off other site/sources. One of their routines checked for
offensive words and then replaced them with PC words.
This receive national attention when their site changed Tyson Gay's
name to Tyson Homosexual.
In my experience most spam can be blocked by case-insensitively
checking for "[url" and "<a". There ain't many spam comments out there
that don't include URLs.
