I'm not sure I fully agree about the GPL thing (I understand and
sympathize with how annoying it is, but when we fight for BSD
licensing then what are we fighting for if not for the right of random
people to take our stuff and without letting us "borrow back"
changes?), but more importantly it should be noted:

People who take MIT/BSD licensed code and strip off the attribution
are actually violating the license. This is pretty much the only thing
you can do that violates the license, but they're doing it. Better
practice is to keep a list of places where code was taken from, and
the licenses governing its use, in your LICENSE.txt file:
