blackList

Component for managing a blacklist of accounts. Contacts of blacklisted accounts do not participate in backup processes.

By using the backup / restore of contacts, if various messengers are installed on the device, duplicate contacts are mistakenly created. To solve this problem, we strongly recommend blocking the following account types by package name:

• "com.viber.voip"

• "org.telegram.messenger"

• "org.telegram.plus"

• "com.twitter.android"

• "com.yandex.yamb"

• "com.facebook.orca"

• "com.skype.raider"

• "com.whatsapp"

• "com.whatsapp.w4b"

• "ru.ok.messages"

• "com.snapchat.android"

• "com.imo.android.imoim"

• "com.tencent.mm"

• "com.icq.mobile.client"

• "org.thoughtcrime.securesms"

• "org.telegram.plus"

• "org.thunderdog.challegram"
