Idiocy
I have two Yahoo email accounts. One of them is because I have AT&Totally Incompetent as my ISP; they use Yahoo for their victim... ah, that is, 'customer'... email services. (I use AT&TI as my ISP only because the only real alternative is ComeLast, and I will never, ever, under any circumstances whatsoever, ever again deal with that bunch of incredibly evil pirates. AT&TI are incompetent; ComeLast is actively evil. And proud of it. If there was an alternative to AT&TI I'd switch in a heartbeat, but there isn't, so I'm stuck.) The other is because I had to access a Yahoo group (no, not one of _those_ Yahoo groups, the only boobs visible are certain of the members of the group, more's the pity) and that was a lot easier from a Yahoo account.
This means that the _only_ real email on my Yahoo accounts are from AT&TI about the wonderful features they want me to pay extra for this month and messages from the Yahoo group. (Usually, unfortunately, from one of the boobs.) And, of course, spam. Very limited spam, as Yahoo is 'targeting' my 'interests' as expressed in my email, and that email is... of a very specific nature. Which means that most of the spam is general spam, mostly viagra/cealis crap and the odd item from our friends in Lagos and their allies. (My favs:
1 the little note I got from Louis Freeh, Director of the FBI, about the $26 million that the FBI had recovered from fraudsters for me. Director Freeh was kind enough to email me from his very own personal Windows Live email account, sent while he was visiting Hong Kong, no doubt on business, and more than a decade after he'd stopped being Director.
2 the other little note I got from Michele Obama on my $26 million grant from her husband's discretionary funds. Mrs. Obama was, like Director Freeh, kind enough to email me from her very own personal Outlook.com account, apparently while she was on a trip to Russia.
Those two are enshrined in my Email Hall of Fame.)
I use AT&TI's account only to talk to AT&TI. I use the Yahoo group account only to talk to the Yahoo group. I don't trust anything which shows up on them except for the limited scope I use them for. I don't trust email from Yahoo in any of my other accounts, usually deleting it on sight. Yahoo has only itself to blame for this.
