People that send group emails using CC instead of BCC.
Mass execute them or not?

YEAH! SCREW THE BRITISH! AMERICA FOREVER, BABY! THAT'LL TEACH YA TO REMOVE DOCTOR WHO!

...oh, I thought you said "BBC". My bad.

Depends on whether the addresses should be visible or not. Yes, it does add quite a bit of length to the message, but that is usually less than what's added when one doesn't trim the "original message" in the body.

What's an email?

They never should be visible unless it's a private closed TRUSTED group. Otherwise most of the time you end up on someone else's spam... I mean mailing list. Huh? Who removed Doctor Who and from where?

BBC removed Doctor Who from all streaming services in anticipation of releasing its own.

The worst e-mail sin is putting the entire text of the previous e-mail (and, if successive senders keep doing it, all the previous messages in the conversation) in your new one. Why Microsoft and other e-mail software makers started making this the default is beyond me, and it appears people are too lazy not to do it.

still got em on my netflix

See, for me it is the other way round. While for private e-mail it usually doesn't matter, back when I was working as a data analyst I'd consider it one of the worst sins not to include the text of the previous e-mail. I'd be emailing hundreds of customers and co-workers and nothing was worse than getting an e-mail like "Sure, that's a good idea. Include it too." from someone and then me having to dig and search for previous correspondance to see what they're talking about.

About bcc and cc, it really depends on the situation. Again at work I'd often have to e-mail person X and make them aware that people Y and Z are also kept informed of the situation. bcc'ing won't do then.

You know, when my girlfriend needs to send me a message, she sends a cable comin' in from above.

Don't need no phone at all.

Don't need no letter at all.

That's right. When I get lonely and I'm sure I've had enough,
she sends her comfort comin' in from above.

Like I said on a post above, yes it's ok and maybe necessary for closed, trusted groups. But when an idiot sends an invite to a photography exhibition to everyone on his contact list on CC, well... let me get my flamethrower. And I just know I'm now on some other idiot's mailing list who thinks we have something in common (perhaps art or whatever).

I'm guessing she also wears Golden Earrings?

Point to JMich. :P

But like a ninja of love rappelling down from above she snuck her way right into your heart!
