PLEASE BE AWARE
WHEN ANSWERING
YOUR PHONE!!!
From a friend....
Interesting!
| just got a call from a 304 area code. Thinking it was someone | know in WV, | answered. It was a man claiming to be from customer service (didn't say what company, only "customer service")
The first thing he asked was "Can you hear me?"| remembered something | saw on Facebook saying people are calling and asking if you can hear them, then using the recording of your "Yes" reply as a way to sign you up for all kinds of stuff. So | replied "I hear you" to which he again asked "so you can hear me?"
Me: | hear you
Him: | just need a yes or no
Me: | hear you
Him: *hangs up*
Thanks to whoever posted that story. | probably would have answered Yes the 1st time he asked.

@paul It's YEARS that PRECISELY for things like these I developed a "NON-affirmative communication system" .. normally here we receive phone calls like "Am I talking with Mr X ?" .. to which I reply "Who is looking for him ?" .. "Are you ?" .. "NO" .. The story about the "YES" is completely true and it's one of the most bastard things. I *THINK* or at least there were rumours about that in Italy they were making a law where "contracts by phone only are NOT valid and require some signature".

@gilesgoat @paul
Those phone conversations must sound like comedy improv games from "Whose line is it anyway?"

@paul that’s why we have the Fernabsatzgesetz.
@eckes Nie davon gehört aber ein Gesetz dagegen klingt gut.
@paul ist bzw war nicht spezifisch dagegen aber er stellt halt die Verbraucher recht gut was Widerspruch/Reklamation angeht. Aber ich würde sagen dieses “ja” ist ne urban myth, die drücken den vertag genauso rein ohne Aufzeichnung weil sie damit ab und zu durch kommen und niemand wirklich international ermittelt
@eckes Verschiedene leute in mein feed haben gesagt sie haben solche anrufe ofters bekommen.Vieleicht hier in Europa nicht, aber England und USA... wurde micht nicht wundern.
@eckes @paul Ich habe mal in einem Telekommunikationsunternehmen gearbeitet, das verschiedenste Subunternehmer zum Verkauf beauftragt hatte. Es ist keine urban myth, leider. Man hat den Vertrag mit einem "ja" ganz schnell an der Backe, zum Glück ist das kündigen leichter geworden.
Ich stimme also dem OP zu, dieses Wort streng zu vermeiden.
@Bakerella @paul man hat die Verträge auch ohne ja leicht an der Backe aber man bekommt sie auch leicht weg bei so betrueriwchen unternehmen. Ich würd als ex Mitarbeiter das übrigens anzeigen
@eckes @paul irgendwie stirbt dieser Begriff nie, aber das Fernabsatzgesetz wurde bereits 2002 aufgehoben. Die Regelungen stehen im BGB.
@julijane @paul es ist eine Deutsche Wortschōpfungsperle, die důrfen wir nicht sterben lassen ,)

@paul Nu is Wiki niet het meest betrouwbaar maar Snopes is dit wel.

"Snopes also analyzed several news reports in which the media interviewed self-identified victims of the scam; in the stories it looked at, nobody reported having been financially defrauded after receiving one of the phone calls. Snopes ultimately classified the claims as "unproven". "

@paul Shit like this is why nonconsensual call recording is illegal in Germany...

  • The few exceptions like Polixe, Fire Dept. and EMS have to record the entire calls...

Also feel free to give the number to #ScammersPayback & #ScamBaiters so they can hammer them with robocalls!

@paul I usually just reply with "Atencion... tres uno cuatro uno cinco... nueve dos seis cinco tres..."

@paul
Doesn’t seem to be any evidence that this is in fact a scam, nor credible ways how recording someone’s “yes” would be useful to scammers.
What’s more suspicious is your use of | (vertical line) instead of I (capital letter i), now why would that be…maybe to obscure that this is just copy&pasted text spread on other platforms.

'Can You Hear Me?' Scam Warning

Dozens of news outlets reported on a purported scam wherein fraudsters supposedly falsify charges by randomly calling people and asking 'Can you hear me?'

@johannes_lehmann | ran the image, on which I found this text, through OCR and posted the result. That accounts for the |s. | didn't do this on purpose. (Okay, here | do hahaha!)
@johannes_lehmann Here is the original. For your peace of mind.

But what's the worst that can happen if you only answer "yes"?

@paul

There are different scripts out there, some with a real human routing the call to recording, but most I get are automated from the start.

I'm death on them if I get a real person.

If it's a guy..I say "Who's fucking your wife at home while you're fucking me on the phone?" And vice versa for a woman. It's pretty common to hear an audible gasp on the other end, before they hang up. They think they have a handle on our culture. I modify their perception. Damned crooks.

They want to stick their foot in my door for a scam, they picked the wrong door.

You can open your eyes, now.

@BrailleScreen @paul Good thing about not changing my number after moving out of state. Most of the time the spammers are calling from my home state. lol
@paul
Why do you use a pipe | instead of a capital I?
@erraggy Because I used an OCR system to read the text from an image and I forgot to replace the pipes with Is.
I had so many comments about this already that I will add #OCR to a next OCR read post. :)

@paul

new to me 🤨😒😒😒 txs the heads up on another scam going around! 👍🏻

@wlf_warren Several people told me it's a hoax. Others told me they experienced this themselves. Better to be safe than sorry.

@paul Yes it is and good to have a heads up on them to know whats up?

They are getting pretty clever w/ how they can deceive others, these scammers, 🤨

@paul

had a group going around in the US dressed up just like 'Publishers Clearing House Sweepstakes' to people's homes, as fake winners had the girls, MC in a tux fake check ballons and party favors the whole charade! scamming older citizens of their life-saving !

*dunno* how details but was in the news and saw it here ( the warning about it )
terrible, wicked people but clever criminals ☹️😠😡

@wlf_warren Nasty folk will stop at nothing, and they'll come up with more and more advanced means to trick us. I'm at the point where I trust no one any more, and that's sad.

@paul The World we live in today, morals just went out the window is very sad and in the long run will destroy this world we live in, I am afraid of that.

I as well, find it hard to 'trust' anyone today is a sad reflection of what we live in.

💯👍🏻agree my friend.

that's the convo and take care around the board and in life lol sadly we all have to do as best we can ☹️☹️☹️
best wishes 🙏🏻

@paul bad enough, wouldn't wish it on my worst enemy, much more the fact of what it will hold for our children 🥺🥹🥲
@paul I've solved this by never answering the phone.
@Kancept This is an option I can live with. 👍
@paul I don't answer the phone unless my phone pops up the name of the caller and its someone I want to talk to. Everyone else can leave a message, and mostly they don't.

@paul In Germany they like to use the trick "Am I speaking with <yourname>?" The answer is always "Fuck you asshole".

Legit people always introduce themself, illegitimate don't have the time for it, they need to call a couple of hundred more this day.
