The newer and more popular thing is cyberbegging, it's happening on a massive scale. I was looking at this guy on Youtube from Switzerland (SwissHumanity) who kept making videos about coming to live in the Philippines and babbling about humanity and saving the world - complete nonsense.
It was clear his only plan was to beg for money online, no other source of income. I expect him to be homeless at one point and the nasty part is - it will backfire on all the white tourists/migrants in the region as the requirements for travel will become more stringent.
The modern backpackers are scum, the ones in Thailand have such an attitude about them, you'd think they've won the Nobel prize.
Asian countries need to become more strict as begging is illegal in all of these countries I believe - arrest and deport, it's best for everyone.
