I heard something similar.  I didn't write it down but someone kept sending a report over and over on some station for a long time as the other station was calling CQ.  It was obviously on purpose.

Hi Bud & everyone,
I can't speak for any one time or frequency, as I didn't track it.
At VP9I, twice on 15m in the afternoon, I had 2 stations, one no call sending a 
serial number and 599 , and another with fake callsign. It was obvious and 
deliberate

Subject: [CQ-Contest] Deliberate QRM During the 2024 CQ WPX CW Contest

Multiple participants in the 2024 CQ WPX CW contest that occurred on 25 and
26 May 2024 were impacted by deliberate QRM (DQRM).  The CQ WPX Contest
Committee has collected observations on the DQRM and concludes that the
source of the DQRM is a single operator using multiple remotely controlled
stations located in the USA.



The following is a partial list of DQRM incidents.  We are asking that
remotely controlled station owners review their activity logs to see if
their stations were active around the times and frequencies shown below.  If
so, it is probable that their stations were used by the DQRM source
operator, and we request that the remotely controlled station owners take
appropriate actions to block future access by the DQRM source operator.
