Whatever you do, don't email anything at all to [email protected]. Especially do not make them aware of "parties with lemons" or "girl in a tub" or "Swedish (SE) goat".
That assumes both competency and an admin that actually wants to effectively accomplish things. The people up top want this stupid shit, the people in the trenches generally either don't give a fuck or don't want this either.
Huge amounts of spam can just be cover for sandbagging if nothing else.
Again, probably not going to be as effective if you do something that can very easily be noticed and filtered out. They're not going to try to translate the Spanish just in case it's an earnest report, they're just gonna delete it and move on. An effective fake report should force them to waste actual resource on investigating it.
Again, not really the point of sending fake reports. They'd just see the Spanish, delete it, and move on. The point is to give them something they'll see, want to read, and want to spend as much time interacting with as possible.
