What do you mean by “you guys”? It’s everyone’s personal choice to post a source or not over here. Personally, I always do except when it was this snapchat dude because I was pretty sure he wasn’t allowed to post what he posted, and I’m now pretty sure I was right.
When I post pictures from Instagram or Twitter, I post the source. If others don’t want to, I respect that. They have their reasons, and they are legit.
All that has nothing to do with posting pictures from David or Gillian’s kids, who btw are adults. One is working on the show, and the other one has now been verified by IG which means she REALLY doesn’t mind.
