Hello,

Any one know why Google AdSense will drop Western Union Payment Method ?

"no", but does it (knowing why) really matter?

Probably because there's either too much fraud involving Western Union payments, because some licensing agreement they had with Western Union expired (and they couldn't agree to terms, or one of the parties doesn't want to), or most likely... less than 1% of users have this as a payment option. Why support a feature that is antiquated?

In fact no, it's just curiosity.

I ask here because I did think that probably google did a statement or something like that to tell why he took this step, and I couldn't find it by searching because of my poor knowledge of English.

@Pixby8
Well this is many good reasons, thank you.

This is the only announcement I have seen, and no mention to why.
