Phishing is a common tool used by scammers in order to gain personal information. Usually, it may come up as a nigerian prince who needs money in order to transport some diamonds. Don't worry, the money will be payed back times ten! Of course, this is a terrible idea, if you give them that money, it is most likely never going to be seen again. Phishing can be bad for the person in question because they can potentially lose vital information, especially an email password, with that they could potentially access every account associated with the email. If there is anything to be learned, do not give a random person your information. Same with a sketchy website.
