It goes more or less like this, once upon a time around 2013 some spanish YN fans had a forum, some users of this imageboard were registered there, one day, they got spammed by h and gore, so some of them said those things were a raid by uboachan.
Some edgelords took it way too personal, came here and posted threats about starting a board war, as result, some bronies who were just passing flooded their forum again, then one of the spanish mods came here declaring war, saying that we were ruining their image, with hilarious phrases like "youtube is my weapon and reason is my boat" in spanish.
Some other spanish developer said we hacked the forum, and the raids kept happening, some time after that, someone inside the spanish community, an ex enemy of the admins, confessed being the one behind the attacks, however, the raids, now featuring scat and shock images and the destruction of the last forum is still a mistery.
The forums were forced to restart four times because of the continuous attacks.
Most of the threads and board war content was erased here, however here's something:
Chesir posts a screenshot about someone trying to blame ubuu and specific users for things:>>>/fg/10377
Here's the spanish mod saying he's done with his war declaration, in the hacked forum:http://yumenikki.foroactivo.com/t747-se-acabo-mi-polemica-con-uboachan
Here we have two of them coming to apologize and being accepted by anons, they are cool guys, it was just a misunderstanding:>>>/ot/13636
There's probably more information in the hacked spanish forum, but that's too much taco for me.
The fun thing about it is that Ubuu was innocent, we were just expectators laughing at the whole mass of irrational and bizarre stupidity happening.
