if you add at least a space before your email

If you'd like to display your email address within your web pages, but are afraid it will be harvested by Spam robots, you can protect yourself. Instead of displaying the usual mailto:you@yourdomain.com, use the following code within your HTML:
<A HREF="mailto:you@yourdomain.com">Contact Us</A>

or make your email address a picture

Well, there are problems with any method although it is true that simple things like this will probably deter the simplest of spider-based email harvesting.

It is still easy enough for someone to modify their harvesting program such that it searches inside links or converts all "somebody AT something DOT com" to "somebody@something.com", etc, replace with any other simple text scheme. It can be done with a simple lookup table.

A good method, from the point of view of keeping spam-mail harvesters out, is to place the email address as an image, but this is actually very very bad from three points of view.

1: Point of view of making the website/forums accessible to users of text browsers.
2: Point of view of conserving bandwidth.
3: Point of view of visually challenged. Since text in an image does not "resize" well, if a person has poor vision and the image is smaller than that person can see, you have alienated that person.
3b: Colorblind people may not be able to determine differences in colors of the text which may make it difficult to read.

I think the best solution is to have two email addresses, one which is the legit email address towards which to send email, and the other which is for spam-bots ONLY (and is either not visible to the users or has big, bold letters all around saying NOT to email to that address, etc)

Then, all correspondence which comes to the "spam" address can be logged and the email addresses blocked from sending email to the regular address. It is going to require that you run your own email server(s) though.

my provider has great antispam filter, i recieve at most two spams a week, usually less.

i have a nice working filter

administrator email has not recieved any spam yet, without an extra protection.

ps.:this looks like PHP

btw.: i guess there are so many methods to hide email addresses from bots, i think noone will prefer writing an algo for each one. they can harvest the un hidden addresses so efficiently ...
