I’ve been using Lemmy for about a year and a half. Rather than limiting myself to content from a specific instance or my subscribed communities I normally look at ‘all’/‘top twelve hours’ and I block communities that I don’t want cluttering my feed. I’ve noticed that some communities like to duplicate across multiple Lemmy instances and often duplicate the posts as well… I created a Python script to analyse and visualise this which you can download from my GitHub. Here is an example visualisation but please note that this is from my ‘main’ account on lemmy.world, not my name account in use for this article.
