Another, more drastic idea that I don't have resources for:
Nowadays many refugee smugglers don't even try to smuggle their niggers to the shore. Instead, they just leave their passengers in a life raft in the Baltic sea, since then the humanitarian organizations demand that they be rescued and brought inland without even needing to hide. My idea: Get a ship, and go out looking for poor refugees waiting for rescue. Get them onboard, close the doors, gas the niggers, loot bodies and dump them in the sea.
And finally, a lighter prank that would probably lead to some good copypasta if someone pulls it off:
Register onto a feminist site with a gender neutral name, and write about how you got molested by a coworker today. How you were in the elevator with a stack of folders, when he started touching your butt, and when you told him to stop he told you to lighten up and licked the back of your neck. Absolutely disgusting. And worst of all, your boss said that that's just what Andrew does to everyone, it's not personal so you should grow a thicker skin. Post, collect as much sympathy as possible, and at some point just offhandedly say something like "Yeah, I have always supported the homosexual rights, but that doesn't mean they can just touch me without my permission." Remember to screenshot everything before this, because this is when the backpedaling starts as everyone rushes to withdraw their sympathy and flip their opinions on how you deserved to be molested after all.
