Billboard hacking

Billboard hacking is when you change or modify a billboard in a way that it was not supposed to be changed. Billboards are those big signs that you see on the side of the road, usually promoting a product or a service.

When people talk about billboard hacking, they mean someone who changes what the billboard says or shows, without permission. For example, instead of reading "Buy this product", the hacker might change it to "Don't buy this product!" just for fun.

Sometimes hackers use specially made tools to hack into the billboard's computer system and change the message. Other times, they climb up the billboard and physically modify it, which is both dangerous and illegal.

While it may seem like a harmless prank, billboard hacking is illegal and can be dangerous if someone gets injured while doing it. So, it's always better to stick to legal and safe ways of expressing your ideas and opinions.
