I'm suspended (understandably), but it's a little complicated

I had a 1/26 draft game. This isn't possible without feeding, so I understand why I was suspended. I made my decision to throw the game with the support of 3 of the remaining 4 members of my team and sympathy from all vocal members of the enemy team.

After four of us had picked our champions, the only one left was our support. He picks Vladimir, which is questionable, but I figured it might not be too bad. He might be going a sorta damage-dealing, kill-stealing support like your average Lux or Pyke support; as I was playing top lane, I didn't really care that much. It's obnoxious and our adc will inevitably rage, but chat can be ignored. We load into the game, Vlad buys Doran's Ring - so not even pretending to be a support, then. He starts to walk bottom, then heads to the red buff I was leashing for our jungler. He autos a few times to pretend he's being helpful, then proceeds to steal the red buff. Nobody gets level two. At that point I was a little tilted; he'd shafted bottom and jungle both, but at least mid and top might be fine, right? Then he goes top and tells me to get out of my lane.

At the end of the day, this game is only a game, so I don't mind the fact that I'm suspended. Ruining the game of someone who tried to ruin the game for the rest of my team felt pretty good, especially considering everyone seemed to support what I was doing. I've been suspended for violations of the Summoner's Code, but I believe the Vladimir in question violated more of the tenets than I did;

1. Support Your Team: stealing red buff. Shafting bottom lane. Taking top lane when queued for support.
2. Facilitate Civil Discussion: denied doing anything wrong. Used abusive (or at least insulting) language.
3. Enjoy Yourself, but not at Anyone Else's Expense: self-explanatory, if you've read above.
4. Build Relationships: "League of Legends is a team game, and, as such, familiarity and rapport with the other competitors with whom you play is going to be a big part of your success." Familiarity and rapport are not words I would associate with this particular player.
5. Lead by Example: what sort of leadership does this exemplify? What example does this set for new players?

The rest of the tenets could be argued with some extra effort, I suppose. And yes, I know my own violations; my suspension was well earned. Given the quality of the opponent I should have had, that was 26 more deaths than I should have had that particular game. Maybe someone can explain to me why action was not taken against this player.
