The spammers' response, of course, will be...

font color="#ffffff"

then...

font color="#fffffe"
font color="#fffeff"
font color="#feffff"

etc..

In addition, the background color can be changed, giving the spammer a whole new set of matching or nearly-matching invisible font colors.

There is a virtually unlimited number of ways to make text invisible or nearly so.
