I'm in the LATAM community on twitter and there's been many posts and more things said since the whole thing started but to give you a summary, at this point it seems the allegations are false or at least just exaggerated. There's been multiple lies found in her stories, and the whole complaint she claimed she put seems to be fake too as Mazino and LEV never got notified of it. The fact that many people that know her have come forward saying she is mentally ill and a pathological liar doesn't help her case either.
Also, there were a few GC players that were supportive of her at first, but as soon as they saw who she was they deleted the support tweets. One of them being bstrdd from Liquid Br.
So after all these things were discovered she lost a lot of credibility, her last posts don't have near enough likes compared to the first too, and she turned off comments as well. So for now it looks like they were just in a toxic relationship where both took part, and so far there's 0 proof of physical abuse from Mazino.
