I guess this how the explosion will happen (as prophets foretold)
Many female avas will instantly change to a male ava, increasing the toxic behaviour level so high that it decides to destroy itself to get rid of the diseases infecting the lounge with their new "identities". After all previous attempts to correct the issue fail, the lounge sees "Supernova-tier" explosion as the only solution to correct the problem.
All this just happens to occur at exactly 100,000 posts.
