I did something!
And it's a website !
More precisely, it is a blogroll. You can enter your profile url, update your profile with the super secret magic string, and click the submit button in order to be added to a brand new and totally unofficial blogroll!
From now on, every time someone will click on the *my super long website url*/random url, he will have a chance to be redirected to your profile!
(The website is running on my own tiny server, I don't register anything beside the url.
The source code of the project is available here
but don't look at it because is it really ugly)
Edit2 (28/01/2021): just updated the design & added a small faq!
Edit3 (15/06/2022): Removed 22 accounts that led to 404 on spacehey :P
