1. Make a fake facebook account. Make the gender of the person
be opposite of your target.
2: Get some friends of yours to add this fake account as their
friend as well to make it look legit.
3: Send a friend request to the person you want to troll.
4: Once they accept, tag the person in a status update that looks
something like this: "I need to get in touch with ANYONE who
has had sexual contact recently with (target' s name). Bloodwork
came back as HIV positive and they are the last person We had
sex with 6 months ago and are now completely ignoring me THIS
IS NO JOKE!!"
