The only answer I can come up off the top of my head (not the GG paranoia nonsense) is that someone is doing it for kicks to tick off users of other boards on 8ch. Basically, denying access to whatever was being posted is enough to send some folks over the edge just to see them act like fools in IRC seems to be entertainment for some folks. Basically, trolls. shrugs

I just find it weird that it's flaring up now is all. There were a couple DDoS attacks I think around December last year (ircc).
