Whoever is in charge of that instance, STOP.
It’s an instance that crossposts posts from Reddit, except it also makes a new user for each Reddit account it came from. So if /u/hello123 made a post, it makes that post under a new account called hello123. That makes it impossible to block posting bots.
Not only that, it makes posts look like they’re posted by real people, with many question and text posts being copied as well. I was very confused as to what these posts were until I realized they’re crossposts.
Examples:
https://lemm.ee/u/pocalyuko@alien.top
https://lemm.ee/u/ItzMeRocket@alien.top
https://lemm.ee/u/CaptainCapp-n@alien.top
I strongly believe Lemmy isn’t the place for mirroring content from other websites. You can host your own alternate Reddit frontend like LibReddit, there’s no reason to spam the posts to everyone using Lemmy just because 5 people asked for it. Not to mention there are already enough instances mirroring posts, this is getting obnoxious.
Seems odd to claim that people don’t understand the concept of using Subscribed to filter their feed, when they’ve made a conscious choice to change from the default to All. It seems you don’t understand the concept of browsing “All” or why people would choose that.
First, the default listing is set by the instance administrator so we can’t be sure of what is the default in the first place.
Second, one of the most common criticisms carried against open source developers is the tendency to provide too many configuration choices to end-users instead of streamlining the interface, which leads to creation of footguns.
Making it so easy to browse by all is one such footgun.
These “lemmy community syncing” tools is also a footgun. The people running those scripts are basically forcing all content from all communities to be copied across the instances. (curiously, if people were not running these scripts, the likelihood of them getting “hit” by alien.top would be quite small).
