You just did this with my ln.tips
2 sats. (I've gotten 1 before though so I don't think 2 is the limit)
I do like getting messages from friends yes.
I have also gotten ads/links to things. This actually is nice when it fits what I seem to be in the mood for already and frustrating when not like a normal ad🤷🏽
Such as once I was posting music links and someone posted their band link and a flyer to their show which was in my area. Then on another post their newest music video, so it was really easy to check them out and just relink all their info.
A QR maybe. But I like the links in the message because on telegram where the notification comes in, it gives me a full preview of if the link is legit or spammy or interesting, or if it's a YouTube video it just plays and such
