It would still be rather easy actually, although admittedly it would be
more work for the spammer. Once you know the font being used and have
a sample of every character in that font (easy) it would not be hard to
write a program to compare blocks of pixels with those which are
already known and to reconstruct the email addresses.
It's just about the simplest form of image recognition.
