How to shit on someone hard

[9]

Let us say we know someone, in person, who we don't like. We know all of their social media accounts, where they work and a good bit of their personal info. What would be your path to fucking with them hard? In any aspect possible, no holds barred. Obviously we don't want to go to prison or just shank them in their sleep, because they have to suffer for whatever reason. 

What's an outline of your moves for something like this?

Use your imagination man. It all comes down to how hard you want to mess with him/her, will you break the law, what kind of morals do you have, what kind of skills do you have (Can you hack, Can you SE...) and how much time you have in your hands . I'll list some things i've seen being done. 

You can buy bedbugs online and spread them in his/her bed. 
You can spread dreadful rumours of him/her.
You can get his/her social media accounts terminated (I've seen methods on this forum for Instagram, Facebook and Youtube.)
Set up social media accounts in his/her name and post racist stuff, lies, pretty much anything that can get him bad reputation.
Become friends with his/her friends and slowly convince everyone to stop being friends with him/her.
Become friends with his boss and slowly convince your boss that his a bad worker, bad person etc. to get him fired or demoted.
If they have a car you can sabotage it (Urethane in the exhaust, unplug sparkplug cap, pour sand/sugar in the gas tank, use a syringe and water to freeze the lock mechanism, slice/empty their tires etc.)

Some more hardcore shit, i don't recommend trying. :monkas:

You can RAT their computer and plant illegal stuff (Terrorist plans, CP, Stolen CC's etc.) and then remove your rat and everything that can be traced back to you.  You can also do this using Arduinos and other tools. After that inform the feds about it (You can do this anonymously) 

You can get his/her credit card information (Set up a fake webstore, Skim it, Pickpocket it etc.) and spend the money on the card (Alternatively you can sell it and make someone else spend the money ) He/She will most likely get the money back eventually but it will take time and cause a lot of problems in their day to day life.

Honorable mention 

In 2015 Zeekill hacked teslamotors.com and completely changed the template and then he got access of Elon Musk's twitter because he had his email on the same domain. This was all to mess with a known swatter Rootworx. He got into a lot of legal trouble and his parents lost their jobs. Eventually his whole family had to move from their old house and change names because people kept showing up and sending death threats.
