I recently had a clear out of my email inbox, as I'd reached about 20,000 unread emails. As a part of this onerous task, I unsubscribed from a large number of mailing lists. Many of them were from online stores where I'd never agreed to be emailed in the first place, but a bunch of them were from conspiracy groups where I'd signed up for more information, or filled in a form to get access to a series of nonsense videos (like “_The Truth About Cancer_” and “_GMOs Revealed_”, two truly awful video series). It was obvious that several of these mailing lists I hadn't even signed up for, so I assume there's some crossover and sharing of mailing lists between these groups. There are also some groups that I've decided to still receive emails from, such as Family First and Voices for Freedom, because I think it's important to keep an eye on them.
