"SG users getting mail on addresses they did not create"; most times this is reported, someone suggests using watchwords. Watchwords aren't worth the effort for my infrequent occurrences, but they sure are weird.
Here's two examples with dates. First address is my own "creation," others are spammer-generated "copies." Both were to entities I judged "likely to spam," although the spam came from other sources. ("Affiliates"??)
All the following precede "<myusername>@xoxy.net":
2004-07-19: toto.1.
2006-08-03: ttoto.1.
2004-07-25: getstuffed.at.
2006-08-07: tgetstuffed.at.
2006-11-20: stuffed.at.
2007-09-01: |getstuffed.at.
Notes:
1. The last address is not a typo. The fiend really did use the delimiter [?] character [the character above the backslash].
2. I stopped using numbers and letters-as-numbers [eg "at"] in mid-2005, so these copycat addresses are easy to spot.
The time lag is what I find most interesting, next to the odd parsing. Any updates on how this works, i.e., is it deliberate or an email program's glitch?
