Powerful Gmail Feature, Adding Suffix To Your UserID

Gmail has an incredibly powerful, yet somewhat unknown feature, that allows you to append a suffix to your userid. This combined with a filter makes for incredibly powerful spam control!

yourid+suffix@gmail.com
The beauty is that you can use as many suffixes as you like, ideally one for each of your services:
yourid+twitter@gmail.com
yourid+flickr@gmail.com
This way (god forbid) if one of these services sell your email address to a 3rd party, it would be very easy to track down the culprit.

So, if I am twitter and I get yourid+twitter@gmail.com then if I sell yourid@gmail.com you would be able to know that I was the one who sold it?

Typically organizations that harvest email addresses and sell them do so in bulk.

They arent likely to be individually checking for this, so if someone gives an address like theirird+suspect@gmail.com, that is the exact email address they will be sold, so if someone other than the company that gave it to starts emailing them it will be to theirid+suspect@gmail.com, so they will know "suspect" was who shared their email with that other entity.
