I like the intiative, but imagine being an innocent forum owner and being SPAMMED with these BFL posts. I would not like it at all. Why hurt those that are not part of all this?
Oh, they'll just be pissed off for an hour or so and will soon get over it.
Might save some poor crypto-noobs house, or car, or family or even his/her entire future and would go a long way towards stopping BFL.
In any conflict there is always a certain amount of collateral damage.
