Although, it is not recommended for people to post their emails in my forum, it still happens. I've thought about using the badword filter to change:

"someone@website.com" to "someone @ website.com"

Does adding a space possibly help at all from SPAMMERS harvesting such an email? I have no idea how these people do their thing. I just feel like this would be an attempt to save my members or people's emails that they post from the junk.

You could use the censor to change the @ symbol to "at" or "_nospamat_", etc.

Email address would end up like someone_nospamat_website.com

I could do that. Right now, I'm experimenting with just adding a space to both sides, _@_. It just seems less intrusive.

This way, if someone uses it like, "I'm @ work." <- Nothing happens.

If they use it like !@#$, it looks like ! @ #$.

So legitimate other uses of @ are not totally messed up but email addresses are a little bit disguised. I'm just not sure if adding 2 spaces actually deters anything, though.

I think this is a great idea. I just tested it with vB (I know this is a Snitz Forum, sorry can't run asp on my site) and it kind of worked. If I type mail@site.com it left it as a link but with the expected result of mail @ site.com. The entire thing was still an e-mail link, albeit useless.

This is a clever suggestion.

I'm sure that a lot of automated email harvesters would trim the spaces.

Yeah, that's what I'm worried about. Maybe the thought is good but it's useless in practice. But in Snitz, it is no longer an active email link so would the spam harvester recognize this as an email?

Trust me. Spam harvestors have gotten very smart. They already search for the @ along with the . symbol. And I am sure they searching for AT and DOT. You know those words we use to try and fool them.

So a simple space to break up the email won't stop them. In my opinion. But I'm no expert on email harvestors.

Can't say that I'd disagree with that.

I'm no expert with spam harvesting bots, but it's my understanding that though spam harvest bots look for familiar characteristics of email addresses in html source, they do not actually render pages nor execute javascript code. I've used something similar to this email Hider before on static pages and it seems effective because none of those email addresses have received any spam (... yet). If you actually view source of the rendered page, the email addy is not recognizable, yet when rendered in the browser works just like an email link. Would it be possible to incorporate something like this with the email post format button.....

how about some lateral thinking? i use a free service called http://www.hidemail.co.uk which creates a small contact form with a unique link of the format: http://www.hidemail.co.uk/form1.asp?H=1000 where H is your unique reference number linking to your email address behind the scenes in a database - never to be reached and harvested by the spammers ... so, rather than posting an email link, a user can post a web link to their unique form. neat eh?

Whats to stop a spammer from writing a script to iterate through 1- 1000 "H" numbers (or even more) and posting it via their system?

You can do the same kind of thing with Snitz already.

I have my business email address on the index page on by business site posted with spaces between the @ sign.
Not one spam email has ever been recieved from it!

In my opinion, using a space on both sides of the @ sign works extremely well.

Just because you haven't received any spam doesn't mean this method works, just that the spambots haven't found your site yet.
