I think its fairly common practice these days not to include a mailto: tag in your webpage. I also realize that a better solution is to have a contact us form.
Recently I've seen some mailto tags that include and HTML encoded email address. Is this an effective way to stop spammers from attacking an email address?
Example:
<a href="mailto:newbi...">email me</a>
Also, are there any other techniques that I've left out? Which is the best method?
From what I've heard, it will help reduce the influx of spam but will not stop it entirely. A minority (for now) of email-address-harvesting bots are smart enough to apply the decoding.
