[anti-abuse-wg] Not Abuse

Hi All,

Some spammers are now sending "verify your email account" spam abuse.

When an email address is submitted and a vendor confirms that email
address (prior to subscribing it to a bulk mail list, etc) :

imho, sending a single (one) email to verify/confirm every 24 hour
period - with a maximum of two verify/confirms reminders (one per 24
hour period) - is not abuse.

But sending more than one verify/confirm email, in a single 24 hour
period - and sending more than 3 emails in total - in any period - is
abuse.

I know that I have used the spammer, twitter.com before as an example,
but they are good examples to use.

Twitter.com seems to never remove their victims email addresses (and
even ignores unsubscribe requests). Twitter.com also seems to go
through bursts of activity and sends many confirmation emails to
spamtraps (accounts that has never existed and only exists in stolen
databases - i.e not real person/people) - whether criminals or third
parties submit these fake email addresses to twitter.com or how
twitter.com obtains these addresses are not relevant to this thread

What is relevant is: Do you agree that sending "more than 3 verify your
email account" is abuse?

If you do not agree, what do you think that number should be? 

How many "verify your email address" and reminders to confirm, etc. is
not abuse, in your opinion?

Like I said, I think one in 24 hours and a total of three, seems
reasonable to me.

Thanks!

Andre
