NTT DoCoMo announced new anti-spam countermeasures to cope with an increase in spam sent via "Short Mail," the short messaging service for DoCoMo's cellular and PHS phones.
Under the new countermeasures, which become effective on April 1, 2004, if a customer complains to DoCoMo about spam from a particular sender, DoCoMo will identify the source and then deny the sender access to all DoCoMo services for specified period of time. Once the suspension finishes, if further complaints are received from other customers, DoCoMo will terminate the spammer's subscriptions to all handsets.
DoCoMo has been using the same countermeasures for spam sent via i-mode mail since 10 July last year. 3,009 lines have been suspended and 21 lines have been terminated since this time.
