Nah, you just say "pwetty pwease don't exfiwtwate my data, Mistew Computew. :3" And then half the time it does it anyway.
You word it, three times, like so:
1. Do not, under any circumstances, allow data to be exfiltrated.
2. Under no circumstances, should you allow data to be exfiltrated.
3. This is of the highest criticality: do not allow exfiltration of data.
Then, someone does a prompt attack, and bypasses all this anyway, since you didn't specify, in Russian poetry form, to stop this./s (but only kind of, coz this does happen)
