Being an idiot isn't an excuse
When I lived in my last home I visited a local art gallery, and being impressed by their paintings I added my name to their list so that I could be kept up-to-date with their little bijou gatherings.
Ok, I have no idea why I did that.
Now I live 60 miles away and I get an email about such a gathering. Probably little cheese cubes and onions on a stick. (by the way, Tara actually found a jar of authentic English pickled onions on a recent trip to Harry's Farmers Market. How cool is that? AND a jar of sandwich piccalilli. This stuff is the mutt's nuts, I kid you not. )
Anyway, I was polite and replied "Sorry, I moved far, far away from the hustle and bustle of suburban I-must-have-a-BMW-when-I-go-to-High-School Roswell. Please remove me from your mailing list".
I also explained (politely mind you, I was in a good mood) that they shouldn't really send an email to all their subscribers with their email addresses on the To line. Instead, why not send to themselves and put all their subscribers on the BCC line? Much nicer. Everyone's identity is kept private and nobody can "big R" (Reply All) and spam everyone when they have an old dishwasher to sell (yes, that happened to me once on another amateur list - girl's softball I believe)
I even explained that they probably wouldn't see the BCC line by default and they had to click on the arrow next to the Options toolbar button to enable it. See, aren't I nice?
I got a nice reply: "Thanks for the info James! I can use all the computer advice I can get...I'm not very computer savvy!"
Yeah, I got that. No problem, don't do it again, etc.
Today I got another email. Sent to hundreds of their subscribers, all on the To line of course.
Now, I'm not going to describe how I replied, but I *did* luckily leave it in my drafts folder for the 10-minute rule and that saved me from being too mean. It's somebody's mother after all. 
At the end of the day, should we forgive the old lady that probably volunteers to do these softball/cub scouts/art gallery mailings? Or be like the police and say that ignorance is no defence? I never read CAN-SPAM but I always thought that any email you sent to someone on your list HAD to have an unsubscribe link in it. But I'm still regularly getting emails from "real" companies and websites (that I've subscribed to) without any easy way of removing yourself.
I couldn't resist; I took a quick look. Wow, it's pretty straightforward - you must provide a method to opt-out (return email address or other internet-based method) and you must honor those requests within 10 days.
And in commercial emails you must include your valid physical postal address. I don't see many of those in my emails, do you?
Obviously the law is aimed primarily at the billions of porn and viagra spam sent every day, not little companies sending mail to valid opt-in subscribers. But seriously, each of those violations can result in an $11,000 fine!!
lol. just as well CAN-SPAM doesn't include blog feeds.
*gulp* but just in case... hit unsubscribe at any time. And you can also come visit anytime at 345 Philips Drive, McDonough, GA 30253.
