Some spammers are very sneaky.
For example, see these posts by 'Michael222':

He started by posting a few generic messages in the Nutrition section on Sep 20th. He came back on Sep 25th and edited his own posts to add spammy links to a commercial web site.
Here's another spammer ('jimmy82') doing the exact same thing.

http://www.cholangiocarcinoma.org/punbb … 842#p63842
http://www.cholangiocarcinoma.org/punbb … 843#p63843

Again, he started by posting a few generic messages not related to CC. Then he came back to edit his own posts. He added spammy links to 'aged care homes'.
I reported all these posts as SPAM long time ago. Either Rick is too busy to clean them up (which is perfectly understandable!!!!!), or he doesn't share my view on what constitutes spam.
These examples of spam are rather benign. It just irks me that some people are trying to make a buck off this site.
