An Easy Way to Deal with Trolls

Riot needs to stop making their game free-to-play because that draws in the most horrid, undisciplined, childish rabble. If you ask people to pay for a subscription, you get more money in the long run by doing that AND skin sales but you also help clean up the community of all the Kids/Trolls/Nasty People, getting rid of the people who are causing most of the problems. Seriously, I know money is not a deciding factor about manners but it seriously makes me wonder why all F-2-P games get plagued with trolls/idiots/foul mouthed people whereas Paid Sub Games actually have nicer communities as they don't feel so self entitled.
