In 2010, Marokai Blue and others "eliminated" Vepres. Compared to Pingvin, would any liberal think Vepres should have been driven off? Thus is the falacy of the "drive your opponents into oblivion" model. Thus why it should be abandoned, including with regards to Pingvin.
Vepres was "driven off" because he was an idiot and became increasingly paranoid during his time on the forum at large. Though I'm flattered that you single me out in giving credit for getting rid of Vepres, I don't understand why we should have to put up with folks that just aren't good enough simply for the sake of filling seats.
And just for the record I have had basically no interaction with Pingvin and know almost nothing about him, so I'm in no way referring to him in this, I'm just speaking about your general point.
