who sends the most unwanted email

For me, it’s LinkedIn.

They send me I don’t know how many “reminders” that everyone I remotely know has tried to add me to their list, even though I’ve never made the slightest contact with their site.

Nothing against LinkedIn (it may be great, for all I know), I just don’t see why I should join yet another time-consuming website. Too much time spent in this medium as it is.
