If you don’t like it, you don’t have to participate.. Everyone participating in the event is spending their time and energy. This is a community mining activity, you can sell the coins you get, it is free.
Of course, I will not participate, you don't have to advise me this

And yes, people who participate spend their time and energy, but on a useless thing. They deserve a reward, but because the result is useless, I call this initiative just wasting. Wasting of ONION on one side and wasting of time and energy on the other side.
But I understand that some people will like it, because it is very easy way to get 1000 ONION, which is still a nice amount of money in some countries.
However, the main question, what is the benefit of this translation effort for the project remains still unanswered. And it is quite sad, considering the total cost of 20 or 30k ONION.
