What is that ref at the end of the link?

Is there any way to prevent search information from being linked to me? Like some way so ad companies can’t even gather than information That would be great

Lemmy is the only social media I have, but we are connected via Whatsapp. I’m thinking that since we were both connected to the wifi without a VPN, that’s the probable source of information bleed.

I’ve always heard it pronounced kway… Is that wrong?
