Getting alerts for my callsign but not online

I’ve been getting alerts for my callsign, K7IV, even though I am not online. They are usually for 20m CW, 30-40 wpm (if only I were that good). I’m trying ascertain if this a spotter error, or if this is someone who is intentionally using my callsign.

Most likely RBN skimmers misdecoding something.
