I get around 10~20 spam emails in my hotmail account each day, but they are now allways sorted into the junkmail folder by hotmail, as I turned my junk mail filtering to exclusive.
I have a address book entry for everyone I mail to, and when new people ask for my email, I add them to the safe list.
I check the junk mail once every 2 days to make sure I don't lose anything important.
Most of the time it just takes a quick skim to see that it's something like "pills to increase your ****'s size", "viagra", "date this *****" or "loans for a house"...
