E-mail Scramblers

Hello all,

<SIGH> I'm soooooo sick and tired of getting spam e-mails. I'm sure that
part of the reson for this is that my e-mail address is publicly available
on my website, ready to be picked by e-mail harvesting programs.

I tried to thwart them by adding a REMOVE_THIS in my e-mail address
(username@REMOV E_THISispname.n et), but the e-mails have not stopped. As for
NG's, I have the return address blocked in a similar fashion.

I Googled for e-mail scramblers but what I found were all JavaScript based.
Are there any non-javascript based scramblers out there, or do I have to go
with a JavaScript scrambler?

Thanks.

This has been gone over many times in many groups. There is no fool-
proof way to prevent email harvesting.

You haven't heard that the spammers run the harvest and remove all these
common words you (the collective you) add to your addys?

REMOVETHIS, REMOVE_THIS, NOSPAM, NO_SPAM, and so on...

You use a valid email address that contains the term nospam as part of
the actual name. Smart spammers will remove the nospam, and get an
invalid address. Unfortunately dumb spammers will not remove the nospam
and will still send you spam. Conversely, people who just click on a
mailto link will get through to you, but people who looks at the
resulting email address and remove the nospam will not get through to
you. I am thinking of changing my address every month - jan2006@ etc.

Once your email address has made it onto spammer's lists the spam will
continue. The only way to escape from that is to change your email
address.

An alternative is deploying client side filtering, this should prevent
you seeing most of the spam, but it will still arrive in your POP box
and require you to download at least the headers.

SpamAssasin is useful if watched carefully - I used that for a few days.
It was much too aggressive and I was not getting some of my client's
emails. I ended up turning it off.

A possibly stupid idea (when has that ever stopped me?[1]):

Get a username, <your_initials> nospam (in Eric's case, "elnospam")
and then post it with "nospam" prepended to it along with the
instructions, "Remove only the *first* 'nospam' to email me."

Spammers who don't try to demung will try to send to "nospamelnospam "
which is invalid. Spammers who try to demung the address will try to
send to "el" (removing both "nospam"s) or "noelno" (removing both
"spam"s[2]), both of which are invalid.

Those who follow the instructions (which spammers never (or seldom)
look at) will send to "elnospam" and their email will get through.

In HTML mailto URLs, you could try prepending "%20" (a space) to the
username in the URL. Many spammers' harvesters treat '%' as a delimiter
and the such harvesters *will* include the "20", making the username
invalid. (I regularly get spam addressed to a %-escaped '/' ("%2F")
in an "http" URL on my anti-spam page.)

While technically invalid in a URL because it contains spaces), I have
found that an email address with inline parenthesized comments (allowed
by RFC 822) will work with most email software. If a comma was part of
the comment text and a spammer stored addresses in a comma-delimited
database, sorting the addresses would break up yours into two pieces.

On my outdated CIH virus page,
http://www.chebucto.ns.ca/~af380/CIH.html
I have the following address encoded in the HTML:

%20af380@( Norman )chebucto( De Forest ).ns( CIH.html ).ca

and have received several requests for antivirus help to that address,
complete with the parenthesized comments. "(De Forest, Norman)" might
be slightly more effective if it caused the address to be broken up
in a comma-delimited list of addresses but I haven't tested that yet.
(Note the leading %-encoded space which should be stripped by conforming
software.) According to RFC 822, spaces *outside* the parentheses are
also allowed but that breaks some Windows-based email software.

[1] That was a rhetorical question.
[2] A few years ago I was a beta-tester for my ISP's automunge feature
for the tin newsreader which appended "nospam" to the username when
posting to Usenet. I was therefore posting as "af380nospa m". To
this day, I still get the occasional spam with multiple sorted
addresses in the "To:" header including "af380", "af380nospa m"
*and* "af380no".

Indeed, and it's not an HTML issue.

There is. Remove all your pages. This won't prevent you from getting
spam, of course. For that, the fool-proof method is to disconnect from
the Internet and never return.

Other methods are just foolish.

If you wish to use the Internet and participate in it, stay tuned to
getting spam and deal with it somehow, e.g. using spam filtering
software. Don't make it your readers' problem.

Well, naturally. They don't just use addresses they harvested *today*.
