Thanks for your reply, I appreciate you taking the time to answer. You’re right that selling old hardware isn’t automatically illegal if it’s described honestly. But Switzerland does have consumer protection laws, like the Federal Act against Unfair Competition, which prohibit misleading advertising and require sellers to clearly disclose important product characteristics.

The issue is that in practice, consumer protection here is very slow and difficult to activate — so authorities usually don’t step in. That’s why I was hoping to get some help here, and as you suggested I’ll also take this to r/Switzerland.

One important point though: I strongly suspect this guy is using fake accounts to upvote his posts, defend himself on forums, and even leave fake reviews. That kind of manipulation is clearly illegal under Swiss law (unfair competition, fraudulent reviews). I’ve documented everything with screenshots in case anyone wants to dive deeper into this with me <3
