Free 3 month trial of WWE Network (usually 1 month) - only valid if you're not currently subscribed or have a non-active subscription.
Fill out the form in the link with a phony name, email addess and phone number -
for the email address I suggest using a disposable email service such as Guerrilla Mail.
for the phone number, input any 10 digit number - don't start the number with 1 or end it with 0.
You'll be emailed a unique link which will activate the trial.
Note: after doing this myself I can see in the account page there is no where it states when your current subscription expires - if you cancel it then I get a message saying my current subscription will expire on Apr 21. From doing some quick research you need to wait until the 1st day of the 3rd month. If you cancel in an earlier month, they just go until the end of that month.
