From the measurement desk
Written for the question you actually typed.
Each piece answers one owner question in the owner's words, with the measured data we have and arithmetic anyone can check.
I answer DMs from my personal phone at 10pm — is that sustainable?
You already know the answer. What owner-as-inbox actually costs, what it drops silently, and the floor that gives you your evenings back.
People ask for prices in DMs and then disappear — were they ever serious?
Measured: yes. Where the price-askers go, why the thread went quiet, and the second message almost nobody sends.
