I doubt freebitcoin got enough advertisement out of this.
We think it has been worthwhile. We got a lot of coverage on the crypto news sites and a healthy increase in volume.
Healthy increase in volume, but lower lottery prize, ignore the period that the first prize skyrocket to 1.8-2.0btc (mass multi accounts bot), it's prize now is lesser than 0.5 BTC (which was before that event is 0.5 -> 0.6 btc) but the wager volume right now is much more than before so either it's not really healthy or the prizes have been offset for weeks to pay the Lambo.
Have anyone won a lottery at Freebitco ? I have tried my luck many times in this lottery but never won it. Even I used to solve the captcha at this site every hour but never got a big reward. Maybe I am not that lucky to go for a Lamborghini
