My own skimmer isn't mis-spotting (locally, I only feed to the RBN;
none of this LPL to the cluster business); though, what LPL's bogus
spots appear to be are image spots; so he's spotting on either
side/multiples of the center frequency of his SDR's center frequency.
Mine will do this when it's misconfigured, or, if the I/Q balance isnt
good and the software hasn't been running long enough to correct for it.
I do notice that it can happen on very loud stations.
Most skimmer ops run using the SCP database so that they don't send
silly spots, and they should only be sending spots that are sending
CQ's. You can turn all of that off though, and it's possible that they
have.
Regardless of what one thinks of his activity, he hasn't had this
problem in the past to this extent, and it's been going on for at least
a week and a half, so I'm a sort of puzzled why he'd let it continue
given the ire he's already attracted in the first place.
The PJ4 station was pretty good about identifying when I was listening
the other evening, but, maybe the code readers are having difficulty, or
more likely nobody is listening and just perpetuating a bogus spot.
Did anyone hear/work JT5DX this morning on 40M? He was *loud*. 10 and
20 over at my QTH and he was relatively easy to work. I stumbled across
him and had to listen for 5 minutes because I couldn't believe what I
was hearing.

Because CW Skimmers pick these up and place them on clusters the ‘slims’ are apparently enjoying this new method of causing trouble. The offenders probably call CQ until they get spotted by a CW Skimmer, and then quit…perhaps to head to a different band to perform the same shenanigans. What can a user do to minimize this?
