Bonus points if it's in a legal way.

Don't be petty and confront them face to face

OP Here, These are not people anyone Should mess face to face but they are incredibly dumb.

don't be a faggot

Petty revenge: Sign them up for all manner of spam, email, snail mail, and voice/text. Just fill out forms for timeshares and ssuch.

Do you have physical access to their computers?

If you haven't met them face to face what could they have done to you to warrant you taking revenge?

Nope, because I have no idea how to hack but i can tell what i know:

Full name;
Current Address;
Facebook (not login info, just their still up account);

I may not explained properly, I have met them, big shit happen... sometime passed and now I want revenge, i waited so no one suspected from me

OP mentioned something legal, so monitoring this thread.

Claim that you are a tranny and were subjected to transphobia by these individuals.

OP Here, I'm an ultra tranny helicopter faggot, now can I get answers?

Not everyone is from Weimerica

Not your personal army.
