First of all, L4s (sorry misspelled in titel) is not a real user, so no harm done here.
It’s an automatic bot xposting from reddit, making this community just as bad as r/technology, which kind frankly only revolves around politics and social media platforms.
I’ve had the user blocked 2 weeks now, and this community is muuuuch more enjoyable and is actually about technology now.
Just wanted to share a positive experience.
How?
There’s a checkbox in your Lemmy account settings to allow/block all bot accounts. Only works if they identify themselves as such, so it’s not foolproof, but it’s better than nothing.
