I use local extension addresses when giving out stuff these days i.e. harry.tuttle+ab97fd5@domain.com. My extensionless email address is not used publicly anywhere. This allows me to find out which nefarious bastard is spamming me. One kind recruiter agreed to settle a handling fee for £220 for 220 emails sent to me over a year. (I don't use recruiters these days but they have a habit of trying to use me still)
