said by KodloN :I can confirm what rebus9 wrote. I'm also using unique email alias for every eshop or service provider registration.
Today early morning I have recieved spam to dyndns email alias.
I have been watching my 'base-ddns@yahoo.com' email alias (the actual account is, 'user@pacbell.net'). But, as with the very nasty Yahoo! leak, I seem to be unaffected. In the case with the Yahoo! leak, victims had to have used a particular, newly purchased (by Yahoo!) service; I had not signed up for it. In this case, I am wondering if spammers have figured out that the 'base-uid@yahoo.com' is akin to a spamtrap; to be avoided.
