Blugger off you blutters

Frank Keating wrote a superb piece in The Guardian this week about what it was like to work for Punch magazine under the editorship of Alan Coren and how it involved long lunches and indoor cricket. But after a couple of highly complimentary comments online the debate deteriorated into a slanging match about Coren's children, the journalists Giles and Victoria. Totally unnecessary and irrelevant to Keating's feature. Is there a suitable name for these poisonous commentators in the blogosphere along the lines of the "green ink brigade" who write nutty letters to newspapers? How about "blutters" as in "nutters", "bluggers" as in "silly buggers" or "blubbers" as in (makes you) "weep".
