We're still seeing cases where a malicious actor, typically in Eastern Europe, will try and sign up a target email address for thousands of lists all at once, flooding their mailbox with confirmation traffic , perhaps to hide some other nefarious issues.
If we could standardize the confirmation messages, at some point, it might be possible to install some sort of circuit-breaker for this kind of abuse, but until then ... we're tending to relegate all confirmations to Junk (not Spam) status, simply out of preservation of the customer's INBOX usefulness.

If it looks like an advertisement with lots of graphics, hidden tracking bugs, etc. it's likely to be viewed as abuse and used by bad guys to harass innocents. I'm very pleasantly (and rarely) surprised with list confirmations that look like this: * A single small logo for branding or no graphics at all * No advertising * A statement like "On [date] at [time] [timezone] you or someone claiming to be you requested to subscribe to [list] from IP address [IP]. To confirm your request, click [link]. If you didn't make this request, do nothing and you will not hear from us again. To report abuse, [do whatever]. Of course that's assuming that the ESP bothers to confirm subscriptions at all. One extremely annoying new trend is websites that grey out after a few seconds and present a popup demanding an email address. This irritation is likely to result in the masses supplying an email address, any email address, just to stop the annoyance. I've resisted the temptation to complete them all with "abuse@<domain of website>". So far, I'm using "nob...@example.com". -- Jay Hennigan - CCIE #7880 - Network Engineering - j...@impulse.net Impulse Internet Service - https://na01.safelinks.protection.outlook.com/?url=http%3a%2f%2fwww.impulse.net%2f&data=01%7c01%7cmichael.wise%40microsoft.com%7c2c9259b781d94431ff5f08d384077b48%7c72f988bf86f141af91ab2d7cd011db47%7c1&sdata=XqQx5DefhhEvuhrne%2f%2bwyze%2fZIC1qFuQ30xW1nlBCv4%3d Your local telephone and internet company - 805 884-6323 - WB6RDV _______________________________________________ mailop mailing list mailop@mailop.org https://na01.safelinks.protection.outlook.com/?url=https%3a%2f%2fchilli.nosignal.org%2fcgi-bin%2fmailman%2flistinfo%2fmailop&data=01%7c01%7cmichael.wise%40microsoft.com%7c2c9259b781d94431ff5f08d384077b48%7c72f988bf86f141af91ab2d7cd011db47%7c1&sdata=DZ0W0hpqF8Pi8yHeS8HhODOAH0wdt%2bzXkgsH6iQ5bG4%3d _______________________________________________ mailop mailing list mailop@mailop.org https://chilli.nosignal.org/cgi-bin/mailman/listinfo/mailop
