Reddit NSFW communities have already started their mass migration to redgif.

redgifs is the porn section of gfycat (old links redirect to redgifs)

It looks like redgifs may have split from Gyfcat (according to wikipedia). Interestingly gyfcat is owned by Snap[chat].

They moved ages ago. Imgur massively limits bandwith for NSFW images.
