 But what are those possible disruptions?

 Previously, Netflix's help-center pages included language about device-specific blocks, as in: If a device persistently accesses an account outside the primary location, then it may be blocked from watching Netflix.

 But the current help-center pages now appear to have removed references to device blocks, so it's unclear how Netflix will be enforcing the restrictions against watching Netflix from a different household. A Netflix spokeswoman declined to comment further. 

Can I share a low-price Basic account with extra members? 

No -- at least, not in any of the countries where these fees have been activated. These "extra member" fees are available only on Standard and Premium plans, which both allow more than one simultaneous stream.
