NYBOY, there are "groups" in Yahoo that are basically mini forums. Yahoo does nothing at all to limit spamming of any sort.
Some, no, MOST yahoo groups have long ago been abandoned by the users and the moderators. One of the main reasons is that the spam messages quickly outnumber the legitimate messages. There are some new groups there but they too are destined to become spam havens. The founder members and moderators who are just folks with yahoo accounts at first do what they can to delete and remove spammers, but after awhile it becomes overwhelming.
Those so called humans who do spamming either personally, or by hiring people to do it at 10 cents a hit, or by using software to automatically do it have absolutely no realizing that I have cursed their mothers, fathers, and grandmothers and grandfathers to the furthest regions of hades. (I suppose that since I've been cursing them so since 1995 or so that some of them have discovered my curse is real, and that is exactly where their actions have gotten their ancestors so placed!)
Much of it originates along the west coast of Africa. I've done some checking. I even used the full headers of spam emails and checked the origin addresses. The ip numerics showed me that there is a single warehouse in Gabon, 5 large buildings in Nigeria, Lagos being spam central in the world.
I then zeroed in using google maps after chatting with a "chat spammer", an actual human, lol, who wanted me to go to a site, even after I told them I have no credit card and that I only use my debit card at the bank for id purposes. Oh the info I got!
Every little shop and restaurant in Lagos has an old computer they use to make an extra dollar or two a day with. They run a copy of a very old spambot program.
They do not give a rodent's rear about the destructive forces they muster.

In a Wired Magazine issue about a year ago was mention that for a very short period the worldwideweb comission of some sort actually locked out all ip addresses originating from Nigeria, but then the few legitimate businesses, mostly shipping companies, in Nigeria complained, calling it a human rights violation, that it was costing them, and that got quickly undone.
I think the spam problem really could be fixed with technology. They could actually pinpoint the actual machine doing a specific activity, at the instant it happens. But they won't. The thinking is that those folks doing it really personally need those 2 american dollars a day...I guess.

Is there not a better way?
Actually, a lot of it also comes from Romania. Those from Romania target the wealthier classes of America, the small business owners. Notice how it is often someone's boss who has their email suddenly hacked? The account hackers are the tricky ones. Happened to me once, but it was a very simple fix for me because they released me, deciding to forget me! I don't have a bank account with 10's of thousands of dollars. shhhph! They saw mine with 28 dollars and 83 cents and said forget it!
And our Turkish Olive tree grower may have been scoped out by the spying spammer type, maybe even government agencies. He's just a grampa gardener ferheaven's sake, but levels and layers look for ways to get what they want, and in those kinds it might not be $$$$$$.cents, but Power&Control, another commodity, a very real commodity. psssssh!
SHOOT! There are entirely new classes and forms of spammers all the time.
Some of them pay to put a BANNER AD up on a site, but then that banner ad has viruses or worms or spybots, or who knows what code, designed to kill your computer slowly...SO YOU HAVE TO BUY A NEW ONE! I think that is what did my old laptop in last year. (It now has a new hard drive in it and a new os and is my backup for internet, but mostly what i use to watch dvd's on.)
