Account sharing
I get a Netflix account over a year ago and terminated my subscription about three months later. I love everything Netflix has to offer but the one thing that interested my was Stanger Things (I rather play games on my pc). So I came back for the second season and the only reason the subscription is still running was because I shared the account this time with friends. The importent point for me is netflix gets the money now every month instead of 2-3 months a year from 2-3 guys so its a win-win for everyone. The short overview I took before writing this is that netflix knows about this issue (it seems to be darker gray in the legal area) but they didnt do anything about it so far. There you have it netflix, you make more money this way, we pay for the four account option, everybody has his own profile and I garantee that you would get far less money once account sharing becomes impossible (honestly, who would even take that subscription without account sharing).
