Personally, my usual approach is to either upvote a creation or move on. Occasionally I see a creation that violates the Terms, I'll flag those and include the reason why I'm flagging it.
The two ways I usually contact imgflip are by using the imgflip feedback form
imgflip.com/feedback or by sending an email to
[email protected] I agree there are users that have abused the downvote button, there's a history of downvote wars on imgflip. I've sent my suggestion in for modifying the downvote system to prevent abuse.
