Netiquettes - Do you think its rude?

[netcat]

Hi All!

I would like to get everyone's opinion on a site my friend showed me. The address is Please learn The Rules Of E-Mail - Use BCC instead of TO and stop forwarding junk. and it is a place to send people when they don't use BCC when sending to groups or forward time wasters to your work address..

Here is my delimma: I am thinking it might be a nice way to let people know I don't appreciate them sending my email address out to a bunch of strangers but I don't want to seem too rude. A lot of the people who send me these kinds of emails are just new to using email or the internet.. What do you guys think? Is this kind of response rude?

Thanks!
