Bots can grab email addresses from your profile, even if you obfuscate it as you do. Viewing your profile does not require a login. If you want to obfuscate it away from bots, but allow the hackers and developers here to email you, consider base64+rot13 then hint to those being used. function rot13() { if [ -r $1 ]; then cat $1 | tr '[N-ZA-Mn-za-m5-90-4]' '[A-Za-z0-9]'; else echo $* | tr '[N-ZA-Mn-za-m5-90-4]' '[A-Za-z0-9]'; fi } echo -n "user@blah.tld" | base64 | rot13 Even base64 may be enough, but once your addy is on a list, it will spread to all the other bots. Another option would be to run your own mail server with your own domains, or set MX for your domains to something like fastmail and create aliases + folders + rules.
