Really interesting thread on Reddit this am about someone getting spammed with tons of emails – like 30 or 40 a minute for an hour. The trick the hackers were trying to pull was to put hide legitimate emails announcing purchases in within the other spam emails.
The emails got through the spam filter because they used a bot to register for email mailing lists from legitimate businesses. So the emails were not spam…just unneeded/unwanted. It would be like if I wanted to burgle your house so I invited a bunch of honest strangers over for a fake party; they all walk in and while they don’t mean any harm they confuse you and you don’t notice me, the burglar. (fun fact – robbing and burgling are two different things. Perks of a cop husband)
