It's really hard to comprehend how entitled "reward which would be the cost of lunch in Sweden can be massive for those low socio-economic-located people" is.
A lunch in central Stockholm is well within 200 kronor. I can't imagine a country where an person with a computer and skills necessary to claim a bounty in cURL would consider that amount massive.
Is he entitled for considering the difficultied from developing countries?
Maybe he's exaggerating a bit with the comparison, but if we consider the ceiling of 10k, that's more than a year of minimum wage in Portugal, or a handful of years in certain developing counties. Certainly significant!
