From imgflip.com/terms:
"Do not spam. Spamming includes posting links exclusively to your own content or monetization, posting malware links, posting irrelevant content, posting lengthy or irrelevant "copypastas", and anything else that is clearly a detriment to the Imgflip community. Spam which is stylistic or just-for-fun such as copypastas is allowed in user-created streams if and only if the moderators of the streams explicitly allow it."
