The problem is that most spammers know how to strip the plus tags, or can strip the dots to associate you across multiple accounts. I think of throwaway addresses the same way as I think of a VPN. I shouldn't be the only person on the domain I'm using, and there shouldn't be any persistent information in the address. With Fastmail, the only information I have to give up is that it is a Fastmail account. I can have `<some_random_string>@fastmail.com`, which makes it much harder for an advertiser or spammer to link my identity from that email to another one.
