Chris Brown's tactics for avoiding spam [LXF156] seem a bit behind the curve!
For one thing, if you are going to give a false email address you might as well make it sound plausible. I give [myname]firstname.lastname@example.org or @hotmail.co.uk, neither of which exist (AFAIK) . Both AoL and MS have given me enough junk in the past so they are due something back. I also created a real Yahoo account that I never look at but gives me a real address to hand out.
But many web sites won't do business unless you give an address that works, because you must first respond to a test email from them. For this situation look at www.spamgourmet.com
. You might be suspicious, but it really works as a free disposable address service. You sign up for an account with your real email address (it's OK, trust me) and an account name, (say "linuxguy", or your real name). When, say, Bloggs Widget Company wants your address, you give "email@example.com". The part before the first period is completely arbitrary, but the "bwc" will identify the culprit of future spam.
Then Spamgourmet will pass on the first 20 emails to you with this address, but subsequent ones will go into their black hole. However you can log back on to Spamgourmet and turn off the tap any time, or turn it back on again, and change the number from the default 20.
The name "spamgourmet.com" can sound suspicious and some companies are wise to it. So Spamgourmet does offer some alternatives. I use "recursor.net". For example Lloyds Bank accepted "spamgourmet.com" but FirstDirect Bank did not, but did accept "recursor.net"
You can also log on to Spamgourmet and see statistics. For me they have stopped nearly 2000 spams in the last year. You can have a spam filter on your own mailbox, I do, but if you know you will have no use for emails from a merchant or his "partners" after the purchase there is no point in even letting it get that far.
