I came across this piece of 'advice'.
Source: here100. Fake a hacker attack. The community of bloggers and webmasters gets in turmoil every time a website or blog gets hacked. If you fake such an attack (i.e., by putting a weird message in your homepage) you’ll certainly receive many backlinks and a bump in traffic. People might get p!ssed if they find out it was a prank, though.
LOL! Maybe it would work for some people, but you'd have to be pretty desperate to use that as a traffic building tactic. And why? What use would the extra traffic be? Maybe you'd scare away the useful visitors. You'd make yourself look vulnerable and people would be scared to trust doing business with you or even leaving details, such as their email address, with you. As for people's reaction to it, I can hardly imagine how my friends would react if they thought my site had been hacked, jumped in and spent their time to help me, and then found out it was only a "prank". Somehow I don't think it would go down very well at all.
This isn't anything that I would want to try. What do you think of the advice?
Edit - of course, giving crazy advice is another way to build traffic, but I don't expect it would do very much to improve your reputation.
