I mean, if you're going to send someone a nude, you wanna make sure you're not identifiable. Rule #1 in the modern world - once it's out there, it's out there.
Definitely a good idea. But not doing so doesn't mean that it's "your fault" if somebody then goes and shares them without your consent.
It's also good practice to keep your thumb over your drink at a party to make sure nobody slips a date rape drug in there when you're not paying attention. But if you didn't do that, and then someone slipped a date rape drug in, nobody* would accuse you of lacking personal responsibility.
* Actually a disturbing number of people would do exactly that.
