Victim-blaming is bad, but there is also a need for discussion of precautions that might have prevented victims from becoming victims in the first place. I think the answer lies in the tone that is used, as well as acknowledgement that sometimes precautions only become clear after the fact, and that victims who don't choose to take all precautions they could (for whatever reason) are still victims who should not be victims.

For example, this lady made what (I think is) a reasonable assumption that a pseudonym was a good enough way of protecting her identity. It wasn't a bad assumption, but because of what happened to her, we should discuss additional precautions so that people like her might fare better in future.

Another thing to consider in this discussion is that sometimes people like this lady know that they are taking a big risk, may end up murdered, but bravely proceed to take their actions anyway.
