Never unsubscribe from spam

A lot of spammers put unsubscribe links at the bottom of their emails or ask you to reply with 'REMOVE' in the subject line. The problem is by clicking these links or replying:

1. There is no guarantee they will actually unsubscribe you.

2. You have actually confirmed your email address is valid and that you read unsolicited mail - this will almost certainly actually generate 'more' spam in your mailbox.

By all means if you did subscribe to a newsletter (i.e. you were expecting the email) but now no longer require it - it should be safe enough to 'unsubscribe' because the company will probably honour the unsubscribe request!
