hi im new here can i take some gifs to make video for my channel or these gifs not for download or i must buy it ??

I reblog almost everything on here, so they aren’t my gifs to begin with. Most of the time when I go to get gifs for a post, I just google sword art online gifs and use what comes up. I wouldn’t just start taking gifs off of here without contacting the originator of the post. I’m sorry I wasn’t of much help!
