Make it cost $10 to make each account.
I've seen this posted a while ago but I'm gonna do it too.
There is this fuck who posted 3 times lately [wanna say his name but naming and shaming is bad] about how he was permabanned multiple times. Now he's made it his goal to make accounts, be as toxic as possible, and get as many people banned as possible.
The best way to avoid this is by adding raw values to accounts, by making them cost money. Currently the toxic trolls can just get banned, make an account, ruin a few peoples' days, get banned, and continue because they lose literally nothing from it.
They would be MUCH less likely to do this if every time they did this it costed them $10.
Now you may be thinking: "But then less people will play LoL if it's not free!" But I think the vast majority of people who will pick up League have already, considering everyone and their dog has heard about the game.
I think the positives vastly outweigh the negatives of this, and it would solve a lot of problems by giving people more incentive to not lose their accounts.
Thank you.
