The agency (FLLU) seem really small. Too small in fact, because most companies would engage a substantially larger firm and have account managers and would handle all of this stuff coherently from one place rather than use potentially hundreds of firms this size (3 people).

Before everyone jumps to conclusions... could it not be the case that someone with just a very small bit of budget said "Wouldn't it be great if..." and then hired this little company "I know a few guys who could..." to help promote it, failing to understand what form that promotion would take.

Of course, it can and should be argued that Samsung (and their many departments and entities) had a tighter leash for their managers and such "little" projects and initiatives... but I wouldn't argue that not having a tight enough leash is tantamount to Samsung consciously trying to bribe users.

This is where I long for journalists over bloggers... perhaps someone could find out who hired FLLU? Then perhaps someone could ask that someone the basis for the campaign and whether it was authorised by Samsung.
