Stop buying from those seller.

Most of the time they sell stolen account.
You can never get rm8 per year. Just happened that netflix allow user to stream 3 device at one time, they provide u with username and password and u can watch while the real user didnt notice.

Try to login via web browser and look at the stream activity, u can even look at the user location.

For those that need to change id every month, most probably the sellers are using stolen credit card info. U can get free 1 month viewing provided u enter your cc info. Tak percaya? Look at the payment info. Every month sure the cc number will change.

Netflix isnt that expensive. U just need to find 3 or 4 friends and u can share with them.

However, there are sellers who manage the sharing account in a legit way. Maybe rm15/month. U can buy from them.

yes , change your password.

for genuine netflix subscribers ,  better change password monthly or check viewing activity proactively .
