Re: SPAM filter on Community's EMail Address?

A few years ago a study found that most SPAM is sent to addresses
"harvested" from the web.  Thus keeping an address off the web is
a good way to reduce spam coming to it.

To reduce SPAM, on my web pages I:

o  rarely use a "mailto://"; link (the kind that sends email)
   since the "robots" that harvest email will pick upt the address

o  do not put addresses on the web in normal format (with and at sign)

o  I usually put addresses in an "obscured" format something like:
   fholson at
   fholson [at]
   fholson at cohousing dot org

o  Avoid addresses like info at     or
   tours at  which can use a common word for a username
   that be guessed by so called dictionary spam

If you do want to use a "mailto://";  you can use an address that requires
manual fixing to work  such as fholsonNOAPAM [at] and then
instruct people to delete the capital letters.  All of these require
a bit of extra effort from the sender but are not as annoying as the
whitelist procedures which I agree are very annoying **.

BTW the archives of cohousing-L which makes web pages out of posts
"obscure" addresses from the body of messages -- the sender's address
is obscured using an image of an at sign.

** If someone requests assistance with their subscription in a way that
requires me to "validate" my reply to get around their spam control,
I typically take that as indication that they dont want my help very
much and I drop the matter...  Whitelists are very effective and
controlling spam (that is effectively why cohousing-L rarely
distributes SPAM), but they are a hassle for new correspondents.
