Yahoo Groups slides further down the spam source slope
I've written about Yahoo Groups' spam problem before and the situation has not gotten any better since 2014. Instead it's gotten worse, as I tweeted:
Yahoo Groups is now refusing to accept bounce messages for their messages, if you had any remaining doubt that it was a spam operation now.
You can pretend to be a legitimate mailing list operation even if
you spew tons of spam with individualized
MAIL FROM origin addresses
(which real mailing list software does too). But this pretense falls
apart when your theoretical legitimate mailing list operation stops
accepting bounces, because the entire reason to individualize your
MAIL FROM addresses is so that you can automatically track bounces
of your messages and do sensible mailing list things like automatically
remove addresses that don't work any more.
(This particular bounce only exists because for some reason this Yahoo Groups email wasn't scored as spam by our commercial anti-spam system. It was recognized as spam by the place the local recipient forwards their email to, so now we have a bad bounce we have to sit on.)
Of course I'm not so cynical (yet) that I think Yahoo is deliberately turning Groups into a spam operation, or at least I don't think that outside of angry moods when I'm especially grumpy. Instead I expect that it is a combination of two factors. First, Yahoo is just not bothering to spend resources on keeping 'unimportant' bits of Yahoo Groups in operation, and that includes the systems that do or don't accept return bounces. Second, I rather expect that Yahoo has no interest in reducing nominal usage of Yahoo Groups by throwing people off of it. Spammers are probably a very major source of remaining Yahoo Groups volume, which means that throwing them off would cause usage to shrink drastically very fast. That doesn't look good. So Yahoo looks the other way; users are users, right? Never mind what they're sending.
(I believe that Yahoo also attaches ads to every Yahoo Groups email message. More email volume, more ads attached, more revenue coming in, the better that Groups and Yahoo looks, and so on. An aggressive indifference to the consequences of revenue-generating activity is not exactly new, in Yahoo or elsewhere.)
There are parts of Yahoo that I will genuinely miss when the whole thing eventually collapses, like Flickr. But I loath Yahoo Groups with a dull passion these days and will be quite happy to see it die, whenever that comes to pass. Hopefully soon. When it happens, it will be good riddance to bad rubbish.
