I use aliases, which are like the plus addressing mentioned by others. Many email addresses, but they all end up going to the same inbox. When one gets too spammy, I update the one service that should have had that email address to use a new alias and then kill off the old one.

Catch alls can be good, but then you get junk to email addresses that you've never attempted to use just because people are guessing what might be a legit email address. I prefer those to bounce so the spammer knows to give up. And even if they don't, I never see their junk that's to some bogus account.

But at the end of the day, spammers and scammers are still a problem. They can be reduced with technology, but the malcontents sill find you eventually when services you use and people you email get compromised.
