I am uninclined to hassle/report job posters if they follow
the tips outlined above.

A couple of further tips for the OP.

- The normal 'delimiter' between message content and
signature is '-- '.  If you add the delimiter, many news
readers will automatically 'hide' the sig., but show it to
the user if they want to see it.

- Signatures going over four lines (like mine at the moment)
can cause people to complain.  I recommend cutting most
of your sig. out to a 'contact' page at your site, then simply
listing the homepage and contact URLs in the sig.

- To expand on what Mark was saying.  It is probably best
to limit your job postings to a single group.  This one would
be the best.  Most of the people interested in Java read it.

In the ads..
- Don't presume your audience knows where you are, but
specifically state the job location and whether citizenship
is required.  (Note that I am Australian - ineligible for most
of the jobs you would likely post).

- Speak to the audience as if they can 'see right through' the
hype.  They can, and will simply point at you and laugh, if your
posting sounds like an ad for the latest, greatest washing powder.
Better still, try to remove anything from the ad that even vaguely
smells like hype - stick to the basic facts.

* Significant, I feel, in that Lew and myself are probably the
most likely people to take some form of action in regard to
posts that are potentially spam.
