Just wanted to mention this
It was bound to happen sooner or later but I started using watchwords today because I noticed 2 addresses that I did not create show up on sg within the last few days. One on the 29th was tv.20.userid@xoxy.net. I have a tv.20.userid@spamgourmet.com I created back in 2003. Yes, not proof positive but odd none the less. The other is somewhat more positive created on the 20th, <part of userid>tv.20.userid@xoxy.net. I absolutely know that I have never used part of my userid in the trigger word and the forwarded messages were all spam. I would not have noticed except gmails spam filters let one through to my inbox.
The short of it is I have been able to go without a watchword for 45 months with no problems till now.
Anyhow, you all have a good day and keep up the good fight.
3,006 forwarded, 170,805 eaten. 204 disposable address(es).
