On a related note, I did a client side (really badly coded) link lengthner 5 or 6 years ago. : https://rickynotaro.github.io/B.U.R.N/

It basically just base64 encode the url to generate the link and decode the url arg to do the redirect.

I also own this email address that I made just for fun: JesuisLeProprietaireDeCeNomDeDomaineTresLongBonjourCaVaBienAller@icirickynotarodemontrealetceciestunnomdedomainebeaucouptroplong.club
