I really hope we don't have to start authenticating to clusters. The hassle to the many global users seems to far exceed the gravity of the problem. Every piece of software that uses clusters would have to implement whatever scheme was used. It would be a mess.

Identifying bad guys by IP addresses is not a thing any more.

I can change my home IP address at will.  Good luck getting Comcast to tell you 
what IP address was on my router 3 days ago.

I can also attack from dozens of countries around the world by using one of any 
number of inexpensive VPN services.

The best way forward is for clusters to start authenticating their users with a 
simple, widely available mechanism like SQRL.

IIRC, maybe 20 years ago Dave, K1TTT did some pioneering work in
identifying self-spotters, I think through the use of IP addresses  It
may be that the same techniques can be used today - or maybe they can at
least demonstrate that these were *not* self-spots. Dave?

For spots, please use your favorite
"retail" DX cluster.

Wow, what a surprise.  I just went and looked at my cluster and sure
enough.

I was running unassisted and I see that I spotted myself twice.

This is not good and the only reason is for someone to ensure that the
cluster logging can't be trusted.

GM contesters.  Hope you all are resting well.

In the FRC chat room we have been discussing the abundance of apparent
self spots during the contest.  Many of our participants who run had
their callsigns spoofed and spots of themselves made. It seems to have
happened to enough of us that the question was posed...   'Was it just
FRC that was targeted, or was it all contesters? "

Looking on this reflector as well as the 3830 reflector, it didn't take
long to see that it wasn't just FRC.

http://lists.contesting.com/archives//html/3830/2021-11/msg00174.html

Curious to know who else out there was targeted.  The were about 10
cases in the chat room I was in this AM, and suspect it might have been
a huge problem.

Is there a way for the sysops to track down the origin ?     I would
think so, but am not positive.

It would be great to nail the perpetrator, and some of us are demanding
it if it is all possible.  Kind of ruins everything for some.
