Hey, lemm.ee requires a valid e-mail address, this is for two reasons:

1. To allow users to recover access their account in case of a forgotten password
2. To combat bot sign ups (requiring a valid e-mail makes it at least a little bit harder to automate bots)

There are several e-mail services that allow “hiding” your e-mail address by generating a new e-mail alias for each sign-up. I recommend checking if your e-mail provider has support for this. For example:
