On Monday I used an email address for the very first time, to submit a
bug, and four days later I received spam at that address (which I have
now disabled). Presumably this is because spammers are crawling the web
and snarfing up email addresses.
Maybe the web interface should rewrite the email addresses to make them
harder for the robots to find. Here are some ideas:
user at domain.net
user<!--
no spam
-->@<!--
no spam
-->domain.net
The latter will look perfectly normal when rendered by the browser,
and will be cut-and-pastable, but might be sufficiently confusing to
the robots (they'd have to correctly deal with entity references, line
breaks, and HTML comments). The former requires human editing before it
can be used, but might be better at confusing the robots.
