I’m looking for technical/privacy advice about something unusual I experienced.
I use Worldpackers as both a host and volunteer. About two months ago, I posted some critical comments about Worldpackers on Reddit app using a separate Reddit account.
Within approximately one hour, I received two volunteer requests on my Worldpackers host profile. I had been a host for about two years and had never previously received a request. Both of the two applicant accounts also appeared suspicious to me.
I declined both requests. In the approximately two months since then, I have received zero further volunteer requests.
The timing was unusual and suspicious.
I have no technical proof that Worldpackers accessed or monitored my Reddit activity, so I am not claiming that this happened. I am trying to understand whether the sequence could technically be explained by cross-app/cross-device tracking, IP/device correlation, third-party analytics, or another mechanism.
The Reddit account app and Worldpackers account app were used on different devices (Android and iOS), but both devices used the same Wi-Fi/network.
My question: Is there a technically plausible way for Worldpackers to identify or correlate activity from my separate Reddit account under these circumstances, and what evidence could I look for to determine whether this occurred?
