That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Earlier today I came across a Reddit comment with a link to an Instagram post. The link had ?igsh= at the end.

When I clicked on the link, I got this popup. It had a name and profile photo that was different from that of the post being shared.

not now

I avoid link trackers. However, I did not realize it was this bad.

To my knowledge, TikTok does the same thing and lists the name of the person that shared the link. Assuming this increases engagement, any website could enable such a feature, even on old links that you shared in the past.

You should manually remove any trackers before sharing, or use an app for it.

I tend to manually strip out anything random hash-looking from URLs. Not so much because I'm worried about identity being exposed, but because it just encourages data-mining and figuring out what causes people to post links places.

There's some open-source app I recall on Android in F-Droid that will do this for a set of known sites, "Link Cleaner" or something.

"Leon -- URL Cleaner". I assume that this is an allusion to the movie.

I also strip off the extension that the Wikipedia app adds to indicate that Wikipedia links are from the app.

I also strip off "m." leading URLs, like "m.wikipedia.org", since that, by convention, forces desktop users to see a mobile version of a site, which is not normally what they want, whereas a non-.m link will still show the mobile site to mobile users.

Latest versions of Firefox offer to copy and paste URL without trackers. I am not sure how it compares to specialized tools.

[–] aleq@lemmy.world 13 points 2 months ago (1 children)

How do I use this feature? I'm a Firefox user since quantum and had no idea this was a thing.

[–] my_hat_stinks@programming.dev 38 points 2 months ago (1 children)

Just right click a link, it's the option directly under copy link.

[–] aleq@lemmy.world 14 points 2 months ago

Never knew it, very neat!

[–] acockworkorange@mander.xyz 2 points 2 months ago (1 children)

Apparently it doesn’t work with YouTube. That’s an elephant sized hole.

[–] CrayonRosary@lemmy.world 1 points 2 months ago (1 children)

Google pays them a lot of money. Are you surprised?

[–] acockworkorange@mander.xyz 1 points 2 months ago

SHOCKED! ~/s~

I’d rather not attribute to malice what is more easily explained by incompetence.

[–] cmnybo@discuss.tchncs.de 23 points 2 months ago (2 children)

There is a Firefox addon called ClearURLs that automatically removes all of the tracking crap. It works on PC and Android.

[–] tb_@lemmy.world 16 points 2 months ago (2 children)

uBlock Origin also has a filter built-in, though you have to enable it. It's under Filter Lists > Privacy > AdGuard URL Tracking Protection

[–] JadenSmith@sh.itjust.works 4 points 2 months ago

Thank you, I had no idea. Already had uBlock Origin on my phone (FF), so that's one less extension needed. Works perfectly!

[–] tb_@lemmy.world 1 points 1 month ago

I assume it blocks something from loading, but I wouldn't exactly know. I haven't looked into it.

[–] TunaLobster@lemmy.world 2 points 2 months ago

I used that so much when I was creating purchase orders. Nobody needs to know how I got to that page.

[–] tb_@lemmy.world 18 points 2 months ago (1 children)

Generally anything that comes after a questionmark in a URL can be safely stripped out, though not always. The random string of characters you get after a youtu.be link is tracking, the ?t=123 is a timestamp.

[–] Ephera@lemmy.ml 8 points 2 months ago (1 children)

YouTube has an even better example of it being problematic to strip the parameters. The original video links look like this:

https://www.youtube.com/watch?v=dQw4w9WgXcQ

The thing is, the stuff after the question mark isn't inherently bad, we just have the convention that the path (/watch) should identify a static resource on the server, whereas the stuff after the question mark is more variable or user-specific.

But YouTube is older than that convention. If YouTube got built today, that URL would look more like this:

https://www.youtube.com/watch/dQw4w9WgXcQ

On the other hand, the URL of a specific search result page would still look the same, even with today's conventions, because it doesn't identify a static resource:

https://www.youtube.com/results?search_query=never+gonna+give+you+up
[–] tb_@lemmy.world 5 points 2 months ago (1 children)

Nice example link you used there

[–] Ephera@lemmy.ml 3 points 2 months ago

Thanks, although I don't believe there's any other link I could've used. 🙃

[–] edgemaster72@lemmy.world 15 points 2 months ago

I also strip off “m.” leading URLs...

Bless you kind netizen

[–] kambusha@sh.itjust.works 10 points 2 months ago* (last edited 2 months ago) (3 children)

URLCheck may be the app you're thinking of.

Edit: the way it works, is that you set it up as your default browser. Then, whenever you hit a link, it will open up URLCheck first, and you'll get to decide what to do with the link, strip away query parameters, and which app to open the link with.

[–] CrayonRosary@lemmy.world 2 points 2 months ago

you set it up as your default browser

You don't have to. You can just copy any URL and share it to the app. Then copy it from the app.

[–] Deconceptualist@lemm.ee 2 points 2 months ago

Omg I've wanted something like this for a long time. Thanks!

[–] otter@lemmy.dbzer0.com -1 points 2 months ago (3 children)
  1. Setting anything as your default "browser" when it's not a browser is only a little sus — "open" source, or no.

  2. Don't share a link if you can't find its complete "verbose" version.

  3. ...

  4. 🤷🏽‍♂️🤞🏽

[–] conciselyverbose@sh.itjust.works 5 points 2 months ago

The reasoning is super transparent. It's the only way it could do what it's doing. 🤷🏼‍♀️

[–] MicrowavedTea@infosec.pub 3 points 2 months ago

How is it more "sus" than setting any other application as default browser? It needs to be default because that's how Android works.

[–] Cheradenine@sh.itjust.works 1 points 2 months ago

You can also set default browser to 'none' then anytime you tap a link a list of browsers and things like Leon, URL check etc. will pop up. In any case they don't require internet access to work.

[–] Asifall@lemmy.world 7 points 2 months ago

Yeah I have a habit of doing this and then testing the link to find the smallest possible version. Mostly because I find it annoying when I want to text a link to someone and it takes up an entire page of the chat.

[–] wrekone@lemmyf.uk 3 points 2 months ago

Leon is great. I try to remember to use it anytime I share a link. As a result, I have found that that some links are just the base url plus a UUID (e.g. mycoolshoppingsite.com/GAJEBKT), so you can't strip out the tracking without breaking the link entirely.

[–] CrayonRosary@lemmy.world 1 points 2 months ago

You're the best!

I just installed it. Look at this perfectly anonymous link:
