Seems related to the hack.
Why?
To me the timing of the Hack seemed more like it already was prepared for some time and only executed now.
What would a lot of new accounts be good for in such a hack?
It seems like the hackers used abandoned forum accounts to participate in the Ripple giveaway.
The giveaway has been suspended for the time being.
I've seen people with more than 50 accs posting in the reddit discussions, so I don't think this is related to the hack. Also, why would they waste their time on ripple?
