I think you are technically still playing the game so I think it's fine. However if you use bots or macros they might ban you for it.
If you are not bored of just clicking every few minute on 5 computers I think it's okay
Hijacking top comment to drop some life math on ya'all.
Let's say you do this, and FF@8 in ARAM as quick as possible. Ignoring queue times, you can earn 30 tokens an hour. Now if you play ARAM normally, the average game is 17 minutes, and assuming a 50% win rate you can earn 21 tokens an hour. So instead of playing the game and having fun, if you decide to "farm" you are gaining a whopping 9 tokens an hour!
Now for the sake of argument, let's double that and say this trick gets you 18 tokens an hour. (It doesn't, but this will just show how poor a use of your time this is) It would take approximately 9 hours to get 160 tokens. In the store, a 10 orb bundle is about $20 and comes with 160 tokens. So if your goal is simple mind numbing farming for tokens, you're better off doing something with your time that can get you at least $3 an hour...
The token gains are designed to be a cool reward for doing what you already would be...playing League and having fun! They're a bonus for play...
