Any way to block spot source by callsign for all triggers?

I’ve been seeing spots coming from a station identified as “W/SWL/TYRONE”. The main issue is that the frequencies spotted are consistently wrong. For example, I have a trigger to alert on my own callsign. Although I’m actually on 14.074, in this case the spot reports me as 14.094588, which incorrect. This is just an example, there are others.

Is there any way to block spots from this user other than by adding it to each of my triggers? I’m sure that this is an issue for others as well. Any suggestions?
