Update:
Earlier, I discovered new domains for Gfycat links, such as "giant.gfycat.com". Additionally, there were some links that only started with "//gfycat.com", but these links would still fall within the scope of the %gfycat.com% DPL query, so there should be no concerns.
These links were found in various calculation blogs. And speaking of which, I have removed all instances of Gfycat links from the calculation blogs, including the newly discovered links mentioned above.
All blogs with "Calculations" categories have been cleared. BUT, there are most likely still calculation blogs that don't have the "Calculations" category.
