WWF wasn't clever with this campaign. It was plain outright stupid and does nothing. How many people that tried on those shirts were people that actually support killing tigers? Of course, none. I've encountered many people that when they get exposed to campaigns like these, they actually form opposite opinion, because there is no need to use tactics like these to get people aware of such things. They will have the idea that, "Well you harassed me with this stupid act, I will do the same to you."
I would say that everybody is aware that people poach animals, if there are people that weren't, I would ask them, "What rock were you hiding under?"
This is the type of campaign that if I was thinking of giving money to this foundation, I would have told them that they screwed up and they won't be getting money.
Seriously, if you can't find a more decent way to raise awareness than scare tactics with blood, give up.
WWF, you crashed and burned with this idea.
200,000 thousand people now don't support tiger poaching, you say?
Well I bet everyone of those people didn't support it in the first place, they just hadn't been asked about it.
