Sort of OFF/ON Topic.
Scamming in general.
Do not reply to an e-mail you suspect to be a scam or from someone to whom you have not given your e-mail address. These scammers have software that goes through billions of web pages "in the blink of an eye" and they sweep up all the e-mail addresses they find that have not been properly protected by the site owners.
Then they send out e-mails to those addresses. Often ISP's will note a large number of e-mails from the same address being sent to their subscribers and will advise their suspicions.
Above all, DO NOT REPLY. That only proves to the scammers your e-mail address is still live. They sell live e-mail addresses to other scammers at (only) $100 per thousand, it makes them a very good profit.

Then you'll get even more scam or spam
