That is an obvious scam, whenever we received an email that asking for funds for some reasons, just ignore them, you shouldn't trust anyone in this virtual world, scammers are scammers, they usually making stories to persuade you.
Lol, although I never get such kind of mail on bitcointalk. However, it makes me laugh when remembering about this similar mail that I receive in my email (which used in freelancing platforms) plus the same method they use several months back. I tried to dig some information from them and after some conversations, they sent me several photos of grandma in a hospital, when I checked those photos on the internet it just fake photos to fool the people.
That's kinda funny when a scammer uses a shitty strategy just to fool other people, scammers have so many ways of scamming people. I have also experience before, I received an email from strangers and he is pursuing me to click the link that he gave to me, it happened because I asked for help in a telegram group and then someone messages me about the link that can help me to fix my problem and then when I already click the link it redirects me in a website which requires me to input my personal information, the website is an obvious fake website because of a wring spelling on their tagline.
