I generally detest MemeGen memes, on the grounds that they aren't funny and reveal nothing of interest or value about the people who do them. However, even I could not resist finding out what Latin case I am:
Wouldn't somebody doing something TO you make you the object of the action and hence accusative? The way it's written implies that "doing something" is the verb-part, as opposed to "giving something to you" where the something is the object.
Basically, yes, although I suppose the person writing this was trying to use 'doing something' as a generic idea to cover a whole range of verbs in Latin which do take the dative as their direct and only object.
