Message harassment

[andrew247]

One in eight people received an offensive e-mail in the last year, [British] government figures have indicated.
The Fraud and Technology Crimes survey by the [British] Home Office also found one in 11 had received similar types of messages by text message or voicemail.

Men aged 26 to 30 were most likely to be the victims of e-mail harassment, the study found.

But women were likely more than men to receive unpleasant messages through mobile phone texts or voicemail.

Almost one in ten women (9.9%) received offending messages via phone, compared with 7.6% of men.

P.S. It's a bit British orientated, but probably still applies mostly worldwide.
