Incoming "I got banned for 3rd Party App Usage for no reason!" complainers soon.
Riot just won a court case against a script/bot selling website and got the list of its entire registry of users as part of its requests.
The $10,000,000 was based off the predicted earnings from the subscription service (which ranged from $15 to $50 a month depending on how extensive of services you wanted).
This places its userbase at around 200,000-666,666 people.
For some reason, I feel like a lot of people will come here to complain about being banned for 'no reason' soon.
