Yahoo seems to have problems in minimizing spam emails and spam IM messages.
SPAM.
In a single week, I am receiving plenty of spam emails on my yahoo. That includes stray messages from my contacts who seem to have accounts that have been hacked.
In addition to that, do not be surprised if you get some “dirty” messages on your YM the moment you log in. These messages also have links which are obviously done by hackers.
It seems Yahoo is not that secure anymore and the same goes for MSN Live. Read more about the reasons why I removed Yahoo Messenger from my computer.
