I got my Yahoo Mail address in 1996 because teenage me thought my address @yahoo.com would be so cool. Nowadays I use it just for online shops, etc (I also use it for Facebook, which is a bad idea, because online shops upload their customer info to Facebook and, tada, guess whose profile matches for targetted advertising). Today I logged in and a stupid ad popped up (I wish I can remember what it was for). When I do a password reset on one of these shops, Yahoo also recognizes those kinds of emails and recommends LastPass or whatever password service they bought.

Incidentally, they've also lost all my mail from before year 2001, when I actually use them for personal communications, meaning all those emails are now lost (well maybe I have a backup somewhere...). What a fucking useless company.
