Thank you for your feedback. However, I might suggest that GIFs are just like words, they're an ability to express oneself in a way that some people feel more comfortable with.
The community guidelines apply to everything within the community and what a member chooses to post. That includes links, words, sentences, images, and yes, GIFs. If a person posts a GIPHY GIF you feel is inappropriate, simply report the post like you would with any other inappropriate content.
The use of GIPHY is entirely optional for individual members. If a member feels offended or upset by something they do a search on, they should just not use the service. And again, if they come across an actual posted GIF by another member they feel is inappropriate to our community and violates our guidelines, report it and we will take a look at it.
