Also,
You are sounding alien conspiracists-ish...Riot wasn't watching your game and punishing you for trolling pregame chat...

Using random is not inherently a bad thing. Waiting till 5 seconds left on the clock and not allowing allies to react to your decision is the wrong part.
Pick random and tell your allies you are playing random as soon as champ select starts, but also be willing to go to the lane they want you to and play the role they want you to play with the random champ.
EG: Support Yi, build something like
early and don't steal all the adc's farm and roam, gank and ward a lot.
Or, Janna top,
, island yourself and keep poking them, don't make your jungler have to gank/camp just to save your ass/tower
Yes, sub-optimal, but you wanted a challenge right?
Waiting till 5 seconds, and picking a random champ is not a 'challenge,' it's just disregarding other people and intentionally not communicating with your team. If anything it's a challenge for everyone BUT you. Cause they are the ones that have to react to it and likely pick up the slack from you not filling whatever lane/role you get optimally.
If you really want a challenge, just play well and improve your MMR, you'll eventually be placed against people who are better than you and force you to get better.
