Applying to this is all about how risk averse you are. As someone who works in Fraud investigation, I really do not like the sound of paying $200 to someone who operates off a gmail account. However that said, those that have applied have not been asked for the $200 which sounds a bit more promising.
I'm not going for it, because I have weighed up the pro's (might get an airline job and build flying hours) against the cons (could be a scam, could waste £1000, would have to beg my other half to move to Indonesia, poor safety record of airline, cost of type rating that would be useless afterwards, and i've not even started looking at other more local options yet).
If you are prepared to lose the initial layout then go for it though because you may strike lucky!
