The social acceptance part is truly hard. I recently received a BS trademark cease & desist because i was using the company name in the e-mail address I provided them & was using to communicate with them.

Personally, i've just replaced the recipient_delimiter default value(+) with "." as that is basically impossible to strip out. Ex, firstname.COMPANY@example.net

I do get a lot of weird looks when handing the addresses out in person, but a quick explanation usually works. I just tell them, that if I start receiving spam from one one the addresses, I can just block it and be done with it. They sometimes counter with "but we won't spam you" and I acknowledge that with "but not everyone is so nice as you" or something like that.

ps: you can use multiple delimiters, so grouping is possible with firstname.bills.COMPANY@example.net
