A bill to combat spam, junk email and nuisance calls is being put forward in June/July in Hong Kong.
This would be great news, as I remember my aunt in HK complaining about Telecom companies, realtors calling up all hours of the day and night. Heck, even I got a call from the telecoms company asking if we wish to avail of blah, blah, blah services. I just palmed it off by saying I'll get someone to call them back.
Plus if this legilsation gets passed, the service is free.
