Please add option that will give possibility to delete/block some accounts permanently.
It will be great if we can delete/block some contacts permanently (without any possibility start to chat with some undesirable contacts by any side. Now blocklist looks more like a "favorites contacts list". So, you can unblock any contact anytime and connect with a person that may cause destructive actions. Especially this "idea" will help to AA and AN keep away from temptations.
Please contact me.
