Silly kid

Gotta start the post off with some serious irony for the style points.

buying accounts utilizes bots which ruin the lvling experience for new players.

And the people who own the bots often have them play on the lesser played modes and que up together to avoid getting reports, which as a consequence minimizes the impact they have on player games. And even if you refuse to believe that for whatever reason do you really think one bot in a game of new/low mmr players is going to ruin a game more than a smurf making every other player in the game irrelevant?

Using a ringer is against competitive integrity

If you actually read my post and understood it was sarcasm you'd understand I actually agree with you on this when I sarcastically dismissed it as not being bad since it doesn't cost Riot money despite potentially being the worst of the offenses yet receiving the least punishment.

Poaching can result in legal action due to the contract most players sign with teams

This is just a mind bogglingly dumb argument to make. It's like saying if an NFL team says a player can't go to interviews unless it's approved by the team the NFL would be powerless to do anything about it because it's in the contract. Guess who makes the rules, regulations, and hands out the fines. Riot could've made a mandatory period where players have enough time to freely put themselves out there to see if any team bites without having to seriously worry about not getting on a team in time. You could've argued that Riot thinks the teams need that much control to keep their investment into their players worthwhile but you go on about that nonsense.
