Could fake bounce with a program? Don't know if it's better than ignore it or not.
@glwxxx
both..
A way to take it up a notch is to include "removethis" or "antispam" or other into the email adress, though even this is picket up and there's an increased risk of real mails accidently not reaching you.
Perhaps instead of using the word "dot" use something like "spot" or "dent" and same thing goes for "at"... could be a simple "át", "8", "a" or "AltGr2". There's an increased risk of this being harvested too if including a non word charracter beforeand/or after these "words instead of charracter" replacements (a simple space would probably help enough for most humans to dezifer something without bots picking up on it). Again there's an increased risk of real mails not reaching you though.
A thing bots surely look for are a row of letters ending with known top domains such as com, net etc. Perhaps adding a special charracter after the last letter or an axtra space in the topdoamin part of the email could help with this? Some goes for very known domains such as hotmail.
So: name removethis a dom ain dent co m'
Surely you would be able to dezifer the above and if you can it's likely that a bot will soon do that too... but it's also at least as likely that a not too computeroriented person wouldn't get it.
Conclusion... have to agree with Piru. Get a good antispam tool and add loads of intelligent (RegExp) filters to it, personaly I use Mailwasher and it easily filters my daily 30 spammails (of witch about 0.5% arent marked, about 15% of with I have to manually remove cause filters cant be to strong on single words alone while the rest is handled automaticly).
