Good for you. I just sent him a msg. Telling him what he could do with his phone call. People like that make me sick. Preying on the vulnerable. Please let’s hope no one is desperate enough to fall for it. And waist money they haven’t got to waist.
What’s the big conspiracy theory? Anybody can click on your username, and send you a private message. What other “details” do they need?
Yes, they can be blocked. Go to the message they sent you, or click on their username, and click: “block”.
But it shouldn’t be necessary, since mods have already blocked that user from posting/messaging.
But it wouldn’t stop them signing up in a new name and messaging people again.
It’s just a spammer - and a persistent one - but they don’t have any confidential details about you. Unless you count being able able to send you a PM - which any member can do - as a confidential detail.
