Make sure, you will have safe but usable e-mail address instead
Javascript is standard coding language, that can be used for encryption of your e-mail addresses.
Even the e-mail is encoded, web clients (browsers) with enabled Javascript allows visitors to use e-mails.
Harvestors (bots) can see only bunch of code parts, thus cannot harvest your email addresses.
Once implemented, bots won't be able to gather the addresses at all. It will not be required to use (at) unprofessional chars.
Bots usually does not have Javascript capability, so no Javascript encoded email can be gathered.
Place the part of the code to any web page with support of HTML, CSS or JS.
The implementation is such quick, that it won't take pretty much none of your time at all.
<script type="text/javascript" language="javascript">
<!-- // No Javascript enabled in Your browser, no e-mail displayed
ML="o:t >a@<mnc/=dreihf\"l.";
MI="753A>?B<C85@D201@9B06=085@9E:08C4@9B06=085@9E:087;54";
OT="";
for(j=0;j<MI.length;j++){
OT+=ML.charAt(MI.charCodeAt(j)-48);
}document.write(OT);
// --></script>
Try the following encoders:
Simple (Easy, quick, effective)
Custom (For really technically-minded people)
HTML Encode (Any HTML that you want to code)
Email encoder
