As far as a safe word being used and ignored. Well it comes down to simple consensuality. Do you consent to that kind of behavior, if you do, then it is acceptable. If you do not, then it is abuse. It's simple as that.

When entering into a relationship with a Dom, are you looking for total slavery, or consensual slavery? If you are looking for the total slave status. Then a safe word would simply be for the Dom to gauge if they had surpassed your ability to withstand something.

There is actually a website dedicated to this line of thinking. I don't subscribe to the ideals, and so I didn't keep track of it. To me, without the consensual nature of the relationship, the power exchange looses it's appeal.
