Recent rhythm game website hackings

[ddr_f4n]

So if you guys remember stepmania.com being hacked, there's been a couple more cases from other (used to be) well known rhythm gaming/stepmania websites that have been hacked recently. Last week Bemanistyle was hacked, and a few days ago ZiV also suffered the same fate (but fortunately managed to bring everything back to normal again a day later, BMS, on the other hand, still have the Front page down).

Now Bemanistyle has been hacked once again. I don't know why they would continue to hack these websites, and if they're the only ones targeted (which is highly unlikely imo). If it's the latter though, what would they have against these sites, or stepmania in general? What kind of vendetta would they have to pursue against them?

I'm posting this in case of any possible further hackings from fellow rhythm gaming sites, especially something like FFR which could easily be a prime target for multiple reasons. I'm honestly surprised this site hasn't been attacked yet though, unless the site was already prepared and managed to avoid the attack already.
