In the last 12 hours or so, several images I posted last night have received 50+ reactions, which is super unusual, especially considering they weren't that good to begin with. I've noticed too, a lot of my very old (9-12 months old) and honestly very poor images are being added to collections. I don't mind it. I just think that if you're going to add someone's work to a collection, it would be a good idea to drop a comment on the image and invite the user to the collection. Or, maybe Civitai could include in the notification what collection the image was added to (assuming it's a public collection of course). It's just a thought.
