A few days ago, I asked about how to properly embed spamtraps in web pages.

Well, noone could tell me if using display: none is appropriate. I actually do not want Google to index the contents in that div. So as long as they don't punish me for using display: none at all, it's okay. And the page I placed the spamtrap on is a doorway-like page for others anyway; it's not part of an important site.

It took the first spammer around 54 hours to send the first spam. Or try to send: all 10 retries with different zombies were rejected by my spam filter. Since then, I've been receiving another round of deliver attempts - around 5-15 per spamtrap address - almost every hour.

Of the > 500 spam delivery attempts I've seen since, none made it through my initial spam filters (not to speak of the content filter behind that), but they were rejected at the SMTP level, even before the mail content was sent.

I've now disabled some of my spam filters to allow the trap adresses to actually receive mail. After all, I want to use them to train my filter. :-)
