Do you need to cease spammers from harvesting the e-mail handle you employ in your web site?
You need to use your e-mail tackle in order that your viewers have a approach to contact you if they’ve any feedback or questions. So it’s worthwhile to put a “mailto:” hyperlink in your webpage.
The drawback is that one of many fundamental strategies that spammers use to acquire e mail addresses is to ship a robotic out to the web whose main function is to seek out e-mail addresses. The spambot does this by wanting on the HTML coding that the browser makes use of to point out the webpage. It then saves the e-mail tackle it finds after “mailto:”.
The two commonest strategies of “hiding” the e-mail handle:
- Munging. In this technique, the e-mail handle shouldn’t be put in a hyperlink. Rather it’s supposedly hidden from the bots by substituting phrases for numerous elements of the handle. Example: johndoe AT hotmail DOT com
-
Encoding. The easiest method to do that is to make use of the usual ASCII coding to switch every letter or image within the tackle with its ASCII code. For instance, the straightforward e-mail handle a @ b.com would seem like:
& #ninety seven; & #sixty four; & #ninety eight; & #forty six; & #ninety nine; & #111; & #109;
( areas added to stop your browser from printing the precise letters )
One can nonetheless use the mailto: hyperlink, because the browser acknowledges this code, and prints out the precise tackle on the webpage.
These strategies not work.
These strategies might have labored once they have been first launched, however one ought to by no means underestimate the intelligence of the hackers who program the spambots. There are new bots that may decode each of those e-mail encryption methods.
These two strategies on no account exhaust the chances. A Google search on “disguise e-mail handle” turns up over two million outcomes. Even discounting duplicate strategies, there are undoubtedly fairly a number of ingenious methods out there.
So what can I do now?
Without going via all the Google entries, I can predict past an inexpensive doubt that the tactic I use myself does a greater job of defending your e-mail tackle than another. How can I be so positive? Because I doubt that any hacker would have the time or talent to write down a bot that might permit him to seize my e-mail handle — it is that properly hidden!
The technique I use hides the handle in a javascript that’s in a separate net file in a totally totally different folder on the web site. It doesn’t seem anyplace within the HTML code of the webpage. Yet it DOES seem on the webpage itself the place anybody can see it — however the bot does not have eyes!
I hear you saying, “But that is unattainable!” Well, it isn’t. Just go to the web site within the paragraph under, and you will discover out the way it’s carried out.
