>spam is spam, don't matter who it comes from.
when I say 'reputable companies' I mean companies that are sending me email for a reason, like I bought something from them and they decided to send me their newsletter but it actually has an opt-out link.
as opposed to the other kind of spam which is about nigerian prince, viagra, oakley sunglasses, you won the lottery etc.
>someone somewhere is going to have easy access to information on you no matter what.
nobody cares about your information specifically. its not like there is a guy at Facebook HQ who walks into his office each morning, goes to the filing cabinet, pulls out Anon's file and has a chuckle about which websites he visited today. they only want to target advertising to you, which isn't the worst thing in the world. the fact that the NSA are doing this worries me a lot more.
