n. (Hacker Lingo) Hacker who uses his or her skills for malicious purposes and/or personal gain. Defacing websites, writing viruses, stealing personal information, and booting people off chat programs are all considered blackhat activities.
The blackhat is loathed by many in the hacker culture, who prefer the chivalrous vigilanteism of the whitehat to the blackhat's destructive and selfish tendencies. However, blackhats generally do deserve respect for their remarkable abilities - the exception of course being the script kiddie.

When you get on FaceBook only to find out that a Blackhat hacker hijacked your account, deleted all your friends, changed your status to "Masterbation exists", and lists all your credit card information/social security, and leaves a post in your wall saying "Yolo".

blackhat marketing is the total opposite of whitehat marketing. You do what you have to do in order to make the sale or close the client. Whether it's exploiting Google by using Xrumer blasts or ordering backlinks from G00B3R.. that's all blackhat marketing.. If it's frowned upon or disliked, it's most likely blackhat and also blackhat marketing can be a quick way to earn money
