Reddit, YouTube, facebook and all of the other social media websites track the urls I copied. Whenever you copy a link, check out, it is not the actual url and/or it contains a track id in the url. I can’t share anything with the people any more, and click their links, because I hate being tracked.
On Android, I highly recommend and regularly use Léon - The URL Cleaner. It’s about as plain and simple of an app there is, just Register Léon as browser (this makes the URL Cleaner app available when you share a link), and set the Action after clean to whatever you like (I set it to Copy to clipboard, then paste from clipboard wherever I’m looking to actually share).
Sure it takes a few seconds longer to share a cleaned up link, but it does exactly what it’s supposed to do and strips all that tracking shit off the links you wanna share.
For a bit more control check out the alternatives list too. URLCheck is awesome
