I once played a game on Android, called Kingdoms at War. Similar concept to Clash of Clans.

Anyway one day I was just minding my own business and building my kingdom, and I got attacked. In this game when you got attacked, you essentially couldn't do anything for a set amount of time if you lost. No biggie, I'd wait it out.

I came back a couple hours later, and I still couldn't do anything. I'd been attacked like a dozen more times. Turned out this bullshit bully guild would go around doing this to people, flooding them with attacks so they couldn't do anything.

Alright, time to get even.

I made a new account, and after about a week of effort I got myself invited to this guild. They didn't know who I was, of course.

I played nice with them, doing whatever I could to help. I gained their trust and was promoted to an officer in the guild after a couple months.

So now comes the revenge. People would do this thing where they would temporarily transfer guild ownership so they could join another guild and help out with wars. They would only do this with people they trusted explicitly for obvious reasons.

About a month later, the owner asked me to hold the guild for the day while he helped a friend out. Of course, I said. No problem.

The second I had the guild, I fired every officer and banned all members. I transferred all gold to a new guild I'd set up on my original account. Then I disbanded the guild and deleted my alt account.

They never knew what happened. Game, set, match you bully motherfuckers.
