We were talking about spam. If you have no objection to i,t then feel free to put your email address about a bit! Perhaps uk.d-i-y is not considered rich harvesting fodder anyway and you will get away with it. Visit some of the more heavily harvested groups and you may not.
We have some clients who have a small office (half a dozen people) where on a bad day each of them used[1] to receive upto 700 spam emails! Most of them result from the actions of a clueless webmaster who published all their (unobfuscated) email addresses on a highly visible and heavily linked to web site. What do you suppose that cost them is lost productivity?
[1] at least before we introduced them to baysian filtering, and updated the web site ;-)As for your physical name and address, yes lots of folks will know it, and many more can find out with relatively little difficulty should they want to. Is that bad? In most cases no. Sometimes it might be if you are unlucky. The more places it is recorded and the more people who know it, then the greater the probability that someone may make improper use of it. I appreciate that does not concern you, however I expect that is not the same for all of us.
Many security breaches can only occur because people are too willing to give away information that they consider to be of little value. After all what harm can it do? However lots of little bits of "low value" information soon add up to to more than the sum of the parts.
