I've been using a similar system, only that I additionally append a random 5 digit number, so that if e.g. [e-mail] gets leaked, that doesn't automatically make [e-mail] easy to guess. Though it does sound like something that might be possible to brute force.

Also, they feed into different subfolders of the same main address.

It definitely has caused some issues, but nothing that would make me regret choosing this system. Obviously the email gets stored in the password manager. And even if not, I just look at the existing emails and check their destination address.

Honestly, the most annoying part is the setup of new addresses. I might look into a way to automate that.

Although it is true that I have not caught a single company giving the email away, but it still helps me keep the inbox organized.

Oh, hey, that reminds me... Any T-Mobile techies reading this?

I know someone who recently was signing up with T-Mobile and discovered that the sales rep was unable to enter their email address in the system because it was rejecting emails containing a dash. They had to give him a different address, and later logged in and successfully updated it to the correct one online. Seems like there is some incorrect filtering going on in whatever UI they use in-store for account creation.
