Sorry to hear you nearly got scammed. There are some right a-holes out there for sure.
Just my little opinion with regards to Ring doorbells and the like.
I have read numerous reports in the press - I know, they can't be trusted any further than your 6'4" Irish chap - about how Ring doorbells are watched by Amazon and they apparently keep records of your movements and other data like that. I wouldn't have one under any circumstances.
Likewise, I'd never have any form of "Alexa" equipment in my house either. Who would allow an open microphone to sit in their private abode listening in to all kinds of conversations, especially one linked to the outside world. Dangerous, or what!? But to go buying an open microphone linked to the internet and god knows where else and leaving it in your private space? Really?
As for FaceTube? Well. I've binned that off completely too.
A little story for you.
I had a company car on order. It was going to kill me to wait the 9 months it was going to take to arrive. Knowing my daughter would drive me crazy, asking on an almost daily basis, "Any news on the car Dad?" for the next 9 months, I decided to keep it up my sleeve. Well, just as the lockdown struck early 2020, I get a call from the office saying that my new car was arriving the next day, and I could go collect it. Whoop! Whoop! I called my daughter into my home office and proudly showed her a picture of my new car on the internet, telling her that we'll have it the next day. Lo, and behold, within 20mins of me showing her the picture, she comes back to me saying "Look what's just popped up on the side bar of her FaceTube page". Yeap! The self same car, and in the same bloody colour! Now apart from liking whatever car Dad is driving, my daughter doesn't drive or take any interest in cars at all. You tell me that big brother isn't watching us.
I know that we are watched all of the time. You can't go anywhere in a car without a camera watching you. Our credit cards tell more about us than anyone would like them too. Etc. Etc. But why make it easy for them?
Moan over.
Sorry, so tired and fed up.
