Oh no!
Since its launch, WWE Network has allowed nearly unlimited use of every account.
This allows one person to buy a membership and share it with family and friends.
However, WWE is apparently cracking down.
WWE updated the terms of service to have this line:
Although your WWE Network subscription is accessible on a number of devices, your use is limited to one (1) WWE Network stream on one (1) device at any given time.
This includes even people who want to, say, watch it on TV and also on their phones or tablets.
