LateLearner, you are in target group of top interest for romance scammers - retired white man from G7 country. I assume you get a lot messages from accounts which represent themselves as Asian females young enough to be your daughters (they are mostly persons kidnapped by Triad, forced to steal from people and detained in mafia bases in Golden Triangle area). I think it's not wise to share any personal info anywhere online such as personal photos, real name, location, birthday... Everything can be used for identity theft.
Beside romance scammers, there are also scammers mostly from West Africa but they don't discriminate too much - they target everyone, but their main focus are Europe, USA, Canada, Australia and New Zealand. If we form our opinion based on their accounts and their fake stories, it seems that whenever families in Africa welcome their 10th children, fathers die and mothers get sick, while children don't eat anything for a few years. When you think about that, it's very disgusting seeing them using manipulation and lies to extract money while there are people who are really in those situations and need help. Same with people who pretends to be Palestinians and wants money to be transferred via for example Western Union.
The third group are Indians with their technical support scams and investment scammers (all across the globe).
Before I get attacked by 'politically correct' people, I want to say that I agree scammers can be from any part of the world, but based on my observations they are mostly from these areas, at least on online platforms. Not all people from these areas are scammers, but sadly most of then who are online are scammers.
All of these groups are racists and psychopats with zero empathy - they don't see white people as persons, they see us as ATMs. Don't send money to anybody online. If you want to help people you can always give money to various charities such as Mary's meals, Caritas, etc.
Personally, much bigger concern for me are minors online and potential threat of paedophilia. It has been already discussed (and downplayed) on a forum started by Follower of Christ, so I won't get much into that issue here. I would advise to minors what I've already said in the first paragraph with addition to tell your parents about everybody with whom you talk online without exception. This is especially relevant for Yue - Asian teenage girl living in a country where paedophilia is relatively accepted (check the facts before attacking me), especially if we keep in mind that a lot of (older) white people suffer from 'yellow fever'.
Last but not least, don't hate these people, hate their behaviour. Also do everything you can to stop them. If you are religious, pray for them, for their victims, for police to catch them as soon as possible and for judges to give them appropriate penalties.
