I once answered the phone to hear a recording of myself saying hello and saying my name. Then it hung up. I never figured out what that was all about. Maybe I'm going to discover a time machine in the future, and prank myself? ;-) > But what scares me is that, if they can call me using my number, then > they can call other numbers using my number, and can get me into very > serious trouble.

Now that such things can be so easily spoofed, I think any legal proceedings needs to use more than just an end-recipient's caller ID log. I'm also concerned that unfaithful logs might be accepted as evidence with more weight than someone's verbal accounts. I've read stories where they've used a google maps GPS log from someone's phone to place someone at a scene, but I've seen how wildly inaccurate mine is. e.g. I've spent an hour at a concert in a park, barely moving more than 50 metres from one spot, yet the logs shows that I've gone on a kilometre trek in a direction I'd not been in (not even in travelling to and from the park). With the fake caller IDs, the huge number of nuisance calls (in my case it could be ten times more nuisance calls than real calls, in some months), I can see the phone system being more and more rejected by customers. I'm dubious about answering anonymous calls, or unknown numbers. Tim: >> Some mail servers let you tag +word to your username, and >> they'll deliver it to your normal address. > Interesting idea.

Here, yahoo does let you set up separate alias addresses, but you have to do that ahead of time. If you do find one that offers the kind of thing that I described (some services call it "plus addressing," but it may use some other symbol than the plus sign, I've seen ones use a dot, or an equals sign), it can be a useful feature. Fastmail and Gmail allegedly support it, and gmail is said to ignore dots in your username. So if your username was johndoe@gmail, you could splatter some dots in different places to track leaks of your address in a similar way (e.g. johndoe@xxxxxxxxx versus john.doe@xxxxxxxxx versus jo.hndo.e@xxxxxxxxx), or use them to simply make combined names more readable. At times you'll find some service that doesn't accept plus addressing, claiming it's for some kind of (crap) security reason. And the chances are that they're a service that already had serious (unrelated) security and privacy problems. :-\ The world is run by morons... As well as for tracking purposes, it's an easy to way to do mail filtering, for those people who can't figure out how to set up email header-based filtering rules. -- uname -rsvp Linux 3.10.0-957.21.3.el7.x86_64 #1 SMP Tue Jun 18 16:35:19 UTC 2019 x86_64 Boilerplate: All unexpected mail to my mailbox is automatically deleted.
