I get a lot of spam ads on Whatsapp from international numbers, it’s annoying but I just block the number and move on. It got worse recently when I started getting sent contact details of supposedly hot blondie’s waiting for an idiot to fall for it, to call the fake number and somehow get ripped off or blackmailed.
The most annoying part is Whatsapp has no option to automatically block messages sent to a phone from people not on their contact list. The spam keeps getting worse and Whatsapp doesn’t seem to care. I’m trying to find a way around this but so far haven’t found any.
