iMessage and FaceTime from complete stranger

I have had the same problem as the previous complainant. I received an iMessage from a @yahoo.com address saying "hi". I then asked who this was and the reason for the message and also how he obtained my number and email. He claimed that he has me stored in his directory as "Abba". I'm certainly no Abba!

I asked him to remove me from his contacts, to which he agreed. Today the idiot messages me again saying hi. I mentioned that I would have him reported, he then called on FaceTime and hung up???? Also sent me a pic of himself!! How do I block him from contacting me, this is rather annoying?

First, the best advice for dealing with a hungry troll: don't feed him.

Ignore this guy, and he will quickly get bored and move on.

If your device runs iOS 7, you can block FaceTime and messages from known addresses that disturb you.

However, if unknown individuals are bothering you with frequent iMessage text messages, you can adjust your Notification settings to ensure that you are not interrupted with alerts when messages from unknown contacts are received (the messages will still be waiting for you in the Messages app, but you will not receive pop-up or banner notifications about them).

To disable notifications for iMessages from unknown contacts, go to the Settings app, then Notifications, then Messages, then scroll down to the "Show iMessage Alerts From" and select My Contacts Only.

Then, ensure that the person who is harassing you via iMessages is NOT in your Contacts. You should no longer receive alerts about his messages (but they will still be received in the Messages app).

Note that this also means that you will not receive notifications about messages received from ANY unknown contacts - you will only receive notifications about messages received from phone numbers or email addresses that are stored in your Contacts. So, be sure to check your Messages app regularly to see if you've received any messages from people not in your Contacts list that you WANT to hear from.

Just as anyone can dial a phone number, whether you have it unlisted or they don't know who you are - anyone can face time or message whatever address or phone number they care to.

With telephones you can block things from the phone company as their software is programed to allow this. With iOS 7, it also can be programmed to block calls from a caller that you don't want to hear from again.

From the settings app, use Message or FaceTime preferences to add numbers to a your devices block list.
