The clearest single warning in this book, and the one that reaches the most experienced readers.
- What it literally says
- That an address is no longer in use.
- What it actually means
- It has left the published set. Whatever it did before, it is not part of the market any more.
- What it does not mean
- That it will stay silent. A retired address carries years of accumulated recognition, which is exactly what makes it worth answering at.
- What to do
- Delete it rather than archiving it. An address kept just in case is one you might paste on a distracted evening months later.
- If it looks different
- It starts answering again. That is not a recovery, and it is the moment this entire entry exists for.
Why this one reaches the wrong people
Every other warning in this book is filtered by experience. This one inverts that. The reader most likely to hold a long dead address is the one who has been doing this longest, has the strongest sense of knowing what they are doing, and is least likely to look closely at a string they recognise.
Familiarity does all the work, and familiarity has never been evidence of anything.
Being precise about what is possible
| Possible? | |
|---|---|
| Taking over the exact address | No, absent a key compromise. Serving traffic there requires the private key it was derived from. |
| Standing up a close resemblance | Yes, and cheaply. This is what you will actually encounter. |
So the thing answering is a near miss: a familiar opening, sometimes a familiar ending, and a middle that differs. Whoever runs it inherits every old post, archived page and bookmark pointing at the original, without doing anything to earn them.
The habit that removes it
- Keep addresses somewhere you control, with the date beside each one.
- Compare against the published set every few weeks. Under a minute, and it is the whole maintenance burden.
- Delete rather than archive when something drops off.
- Check the middle of any address you did not paste from a current list.
