Re: Tracking the WhatsApp habits of random smartphones

I've been using WhatsApp for years, reluctantly since it is the de-facto SMS standard in my country. I will never, ever, understand the "online" status feature. It is ridiculously invasive and cannot ever be turned off or even hidden from specific contacts. This is a SMS client, not a chat client, and revealing a user's online status is highly problematic both socially and security-wise. I can't help but wonder how m…

I totally agree. Except that I very much call it a chat client. It is way beyond SMS.

I only used WhatsApp for a year or so to talk to a specific person, but it definitely felt like a chat client to me. My general impression is that it is a lesser version of AIM but using phone numbers as logins. To be fair, I think of all instant messaging apps as lesser versions of AIM, and I still can't believe AOL dropped the ball so hard on that. I don't remember the online indication, is that only when you're ac…

When you are online anyone can check it. There is no option to hide the online status. Using an easy script anyone can then spy and understand pretty much everything of a person, or a group. This is easy cyber stalking and dangerous. Especially because normal people do not understand this and think that hiding last seen is useful to avoid being stalked…

Any app that gives my peers even an inkling of what I'm doing without me explicitly sending that information gives me the heebie jeebies.

I've gone back to using SMS for messaging these days. No more read receipts, no more "last active 10 minutes ago", no more "Alice is nearby!", and no more "you haven't messaged Bob in a while, send a message?".

Sure SMS is insecure, but at least it doesn't drive me insane with all the bullshit of so many messaging apps.

Not in France actually, we mainly use WhatsApp as a main message app; nobody uses SMS nowadays

Well I do use SMS, as well as my friends and family in France. I use WhatsApp with Belgians (I live in Belgium) because SMS's are not free for them, and also for sharing photos because MMS is a mess.

true, my point is more about the tendency of using groups of people to quickly share. Which SMS does not do properly.

The most interesting part to me wasn't the technical details but rather the MAU, WAU, DAU stats at the end from random sample. Way fewer people than I would have expected use WhatsApp on a weekly basis.

This is in France, where text messages were free (unlimited with your subscription) long ago before we had internet on our smartphone. Thus people use text message a lot and did use WhatsApp only to contact people outside from France

Text messages were around €0.10 for most plans until 2012 though (due to the unlawful collusion of telcos).

You can absolutely hide it - it's in the settings, as mentioned in the article. The tradeoff is you won't be able to see anyone else's status.

I do agree I don't particularly like that it's on by default.

And this is just the tip of the iceberg. As described in the article, you can avoid this by hiding your "last seen" status.

But why use the "last seen" feature, if WhatsApp also has an "online" indicator? Funnily enough, that one can't be disabled and is visible to everyone! That has been criticized for over 5 years now, with no reaction from whatsapp/FB.

There was even a similar tool back in 2016 which used this "online" indicator instead, called WhatsSpy [0]. It's no longer maintained, but you can see screenshots of it on this old German article [1] or you might be able to find English articles as well.

I don't know of any current tool which does this, but I'd guess there are a few out there, since it's so easy to do and can't be prevented.

> Privacy setting for Last Seen: Set by default to Everyone and nobody configures it. It surprised me that only 10% of his random (French) sample is active daily (179/1751=10%). In my contacts, I do see people who have accounts but haven't used it in weeks, but it's not the norm. However, I see lots of people in my contacts who show no info for Last Seen.

Hiding last seen is useless as the online status cannot be hidden. There are various apps that exploit this for money so you can stalk anybody…

Totally agreed that it's invasive. Same for the "typing" indicator, which also can't be disabled. If I'm writing something longer than a sentence or two, I usually just compose it somewhere else and then copy/paste it into WhatsApp, just to avoid feeling observed.

The fact that those two things can't be disabled actually makes me want to use WhatsApp less. I doubt I'm alone in that. Makes me wonder if Facebook's "engagement" stats account for those types of disincentives.

His script start from the bottom of 06 XX XX XX XX (french mobile number) and increases. This is not the most efficient way to have working/active numbers. As he said, starting with 06 numbers are saturated by now and we opened 07 XX... numbers. Thus, 07 numbers are more likely to be fresher et more used by "younger" people. While first 06 could be more used by professional and "older" people As I said in a previous…

good call about 07 numbers being more attributed to youngers. I took the 06 range to maximize the chance to get valid/active numbers.
