I use Element Inspector but I work directly with source (option view source in Chrome Browser) since it seems, the spammers search using this plain code, don't they?
Apart of this in the page:
I am not sure where those email_content elements come from.
That Email Protector is not picking them up could either be because the html is placed there after Email Protector has looked at the html (matter of system plugin odering).
Or because of the '%20' after the email addresses, which shouldn't be there in any case.
