I think it's pretty crazy that GMail, from my main account, doesn't let me just make a high-entropy word (buffalowafflesloth) and a tag, so that that email is instantly associated with the tag on my end. It should take me literally 2 clicks to write "hackernews notificaitn" and receive "buffalowafflesloth" in response, meaning anything sent to "buffalowafflesloth" gets to my main email with the "hackernews notificaitn" tag. (And I would give this service "buffalowafflesloth@gmail.com")
Google: if you're reading this do this. Let us give out emails that get a tag, so that later we can redirect it. You already kind-of do this with +SOMETHING but the +SOMETHING part can be removed to get the original email.
I don't need to lock my door either, but that kind of security doesn't scale. I either use mailinator for throwaway email signups, or I have a spam gmail account.
But I'm not going to give out my main account+marker if I expect to want to be able to undo sharing my email in the future at some point that I try to follow an unsubscribe link and it doesn't work, or because my email might get sold: that's just downright silly. You think the kind of people that would sell email lists wouldn't run a regex to strip +spam markers from gmail accounts?
You literally have to apply a one-line regex to do that. It's security by obscurity. Anyone working at google should understand that.

everything I wrote applies only and specifically to gmail. it would be trivial to strip the +'s from every gmail address to get right into the person's main inbox.
If I don't trust a person to stop spamming me or sell my email address then I'm not going to trust a person not to do that.
I was saying that regarding to automatically stripping out +string from the email to thwart this. Gmail uses them as a special character, but it is a valid email character, along with all these http://stackoverflow.com/a/2049510
There is mailgun, there is gmail api, there is programming.
but if you think security by obscurity is enough that I should use a solution that instantly stops working once lots of people use it, then more power to you. I'm not going to do that.
also I use gmail because I don't run my own mailserver. I'm not about to start coding.
