I may be the only one with the following experience so please bear with me.
I use lastpass to generate passwords and save my credentials to use on websites/apps. While for many sites I will never use the site again, in some cases after some time I find myself back on a site I had registered on before.
It may be because the site has added new features or it could be because my condition has changed. (I would like to say I came back because of the work that the website owners did in marketing/new features etc).
I am not involved in this sort of thing from day to day but I think that one should also track "πππ π ππππππππππ πππ π ππππ πππ π ππππ πππ πππ ππππ πππ ππππππ ππππ ππ"
