You should include who made the gifs if you are going to repost them. Only fair.

I’m already trying to trace the gifs back to the owners when possible to make a list for the page. In any case, the first thing I made clear after creating this blog was that 99% of the gifs are not mine and I absolutely DO NOT claim them as my own, ‘cause I know the work behind it and I hate when people try and take credit for something they didn’t do. I know the feeling ‘cause I create graphics and I often find out people reposting my works and editing them without my consent. If you know the owners of some of the gifs I posted, please let me know, it would be very helpful :)
