Anti-Spam Email Tricks

Don't you think robot-crawlers, that in the past, have been programmed to look for strings that contain an "@" symbol, for harvesting email addresses for spamming purposes, have been re-programmed to include:

"me [at] mysite.com"
"me @ mysite.com"
"me@TAKEOUTmysite.com"


I can't believe people still use these techniques to avoid spam.
