For starters, BrikoX should just stop doing that, and only post in one community. People interested in it will see it (like you do now). If he/she is reputation farming, then this is also not beneficial to him/her. Because this way there is less interaction on the topic, as it is now fractured.

There are more technical ways to implement something like others have mentioned, but this will not be easy and is currently not a priority. I'd say, put it in the backlog and built something for it in due time. There are so many scenario's to manage when for example creating a bundled thread and showing cross posts. The first challenge being identifying the duplicates. Because it will not just be one user posting, nor are the users necessarily linked (e.g. This could be BrikoX@beehaw, BrikoX@lemmy, etc..).
