WhatsApp has been suffering from some intensive spam, and for that reason, it has been taking banning accounts seriously. With this, though, some users might have actually gotten their account banned without spreading spam. Now, a new feature, currently under development, will make un-banning your account easier.
The feature is currently seen as a hidden one in the beta version of WhatsApp and is yet to become publicly available. It will allow a user with a banned account to request a review of the situation from WhatsApp’s team.
Of course, if WhatsApp finds the ban was accurate, it will not remove it and you will need to register another phone number if you want to use the chat service. The feature has been spotted in the beta for iOS, but it will most likely be developed for Android as well.
At the moment, it is unclear when this feature will make its way to the general public.
