Players do not care about their smurf accounts and will leave the game ruining it for players in lower ranks. Giving an IP banned would prevent players from trolling and doing things like that on their smurf improving the gameplay of lower ranks.
An IP ban can be circumvented fast these days. Some internet providers also work with dynamic IP's making the whole IP ban idea not effective.
Not to mention those who play at PC Bangs/Internet Cafe's or are at their Campus/Education etc.
As already pointed out, IP ban would have zero impact on the game, it requires no special skills or effort with the vast majority of providers to change your IP (which in most cases happens automatically when you reconnect to the provider).
I believe they should give each player a behavior score and given a lot of benefits to good behavior.
For example for match making, good behavior players get matched up and have priority in the queue and auto-fill protection, while poorly behaved players get tossed in with each other.
You could have a system of approval levels of behavior. For example you can queue by saying anyone with a 90% positive score or higher, that way though you might be in the queue longer you are guaranteed to play with well behaved players.
I also think the rewards for having high honors and good behavior should be extremely high. For example double essence for leveling, special reward tiers, advanced access to newly released champions, invitation to "good behavior" divisions and leagues.
Make it so that the benefit of being well behaved are so good, that players willingly change their attitudes so they can gain access to them.
I also think that people with high honors and a good behavior rating should have more impact when reporting people and people with bad behavior, should have their reporting impact and priority significantly reduced.
Punish heavily without banning and reward good behavior, that is the theme to how to fix a toxic community. It would not only improve the behavior but eliminate the benefits and logic of creating smurf accounts.
The last time they tried an IP ban (~S1 or so), it knocked out an entire college dorm. They're not going to do that again.
Are you for real? Why shouldn't dodging on someone's main have the same result? Biased much?
If only the game wasnt f2p these problems wouldnt be as prominent.
You can't IP ban because of DHCPs.... Read about it.
Or you know just prevent smurfing in general. But they help make Riot's number look better, so that'll never happen.
