Sure, they could block based on your VPN provider, but they’re probably also using Deep Packet Inspection .

The ELI5 verson: It’s possible to just “watch” your traffic and notice that it’s not the “normal” https traffic (which is the most common traffic) . This can be done by finger printing the request itself or just watching the amount of traffic. For example if you “visit” a website, but upload and download 3 megabytes of data and it takes 15 minutes to send/receive that data… well, that looks suspicious… and depending on the country, you may have some people knocking on your door.

All aboard the gold train!

Since you asked:

1. The bot provides little “value” vs the noise it creates.

I don’t need a bot to tell me that the BBC is a legit news source. Maybe if you flip it around and only publish a message if it’s a known scammy website, this might be less spammy. However, this “threshold for scamminess” would be very subjective.

2. This bot is everywhere. This is closely related to the first point (“value” vs noise). It just sprang up one day and I saw it in every single thread, I’d read.

Fortunately, most Lemmy clients allow blocking users - which I’ve done and I’m much happier with my Lemmy experience.
