Verify every time or not
Almost nobody decides to stop checking. They decide once that this particular time is fine, and then that becomes the habit.
Every single time
- What you gain
- The only defence that works against a convincing copy, applied when you need it rather than when you remember.
- What you give up
- Under a minute per session, plus an hour of setup once. The real cost is that it feels pointless for months at a time.
- Suits
- Everyone. This is the closest thing to a rule on this site.
Only when something feels wrong
- What you gain
- Almost no ongoing effort, and it catches the obvious cases.
- What you give up
- A good copy produces no feeling. That is the entire point of building one, so this policy is absent exactly when it was needed.
- Suits
- Nobody, though it is what most people actually do without having chosen it.
Never, and rely on the address list
- What you gain
- Nothing to learn and nothing to maintain.
- What you give up
- You are trusting whoever published the list, permanently, including on the day the list is wrong or the page is not what it appears.
- Suits
- People who accept they are trusting a third party. Worth being honest with yourself about, rather than pretending otherwise.
Why the middle option fails
It assumes a copy feels different. Sometimes one does, and a vague sense that something is off is worth acting on. But the copies worth worrying about are copied wholesale, load faster than the real thing because they carry no load, and open on the characters you recognise.
So a policy of checking when something feels wrong is a policy of checking against amateurs and not against anybody who put effort in. It produces confidence without the coverage that would justify it, which is worse than having no policy.
What it actually costs
| Time | |
|---|---|
| Establishing a fingerprint from independent sources | About an hour, once, ever |
| Each check afterwards | Under a minute |
| Reading the output properly | Two seconds, and it is the part people skip |
What tips it
Nothing, honestly. This is the one decision on the site where the options are not balanced, and the page exists to show you the shape of the failure rather than to present a genuine trade. The useful thing it can tell you is why the habit decays: it produces no visible result for months, and then produces the only result that ever mattered on one evening you did not see coming.
The people who lose accounts are rarely the ones who never learned this. They are the ones who did it for a year, got comfortable, and quietly stopped.
