Every time someone likes a video or photo the video/photo is publsihed again and again?
So as well vidos and phots are published many many times in activity stream.
QUESTION: is it possible to limit likes only to a message like user xy liked the photo or video of user yz?
Has anyone a good suggestion?

Hi
I am not sure what to do you mean by publishing again?
When a user like an item it appear as an activity only. For example, I liked a photo and it appears Pankaj like xxxxx photo.
The photo is already published on site it's only the activity stream.
For the Likes striction, sorry it's not possible to restrict the likes to specific items only, you need to hack the core files to modify the codes for this.

Regards
