Spammers will make spam as long as they can get money from it.

Maybe I do not understand this. Nevertheless let me cite this statement
from wiki.creativecommons.org/Frequently_Asked_Questions .

|    the noncommercial license option is an inventive
| tool designed to allow people to maximize the distribution
| of their works while keeping control of the commercial aspects
| of their copyright. To make one thing clear that is sometimes
| misunderstood: the "noncommercial use" condition applies only
| to others who use your work, not to you (the licensor). So if
| you choose to license your work under a Creative Commons license
| that includes the “noncommercial use” option, you impose the
| ”noncommercial” condition on the users (licensees). However,
| you, the creator of the work and/or licensor, may at any time
| decide to use it commercially. People who want to copy or adapt
| your work, "primarily for monetary compensation or financial gain"
| must get your separate permission first.
