So, after seeing this question on stack overflow...

I want to capture address given on the contact us page. Is

us page. I am able to get content from contact us page. but i
am quite confuse how to get only address from this page.'''
.. and preceded by seeing 50-100+ projects advertised (daily)
to scrape contact details and create databases for spam
purposes on most freelance websites - I quickly come to the
realisation that with Linked Data, the tasks of these people
just became a whole lot easier, indeed the data is all MRD for
them and linked up to more.
Thus, in addition to nudging at general awareness of these
issues, I do wonder who (if anybody) is working on spam (and
unethical usage) solutions for the web of data?
Agreed, it's quite easy to make a very effective spam filter using LOD
Entity -> Spam Rank
Unknown Entity -> Spam Rank = 0%
Has WebID -> Spam Rank = 50%
Has WebID in LOD (e.g. sindice) -> Spam Rank = 75%
WebID is 3 links away from you -> Spam Rank = 85%
WebID is 2 links away from you -> Spam Rank = 90%
WebID is one link away from you -> Spam Rank = 95%
It's not perfect, but you can go from zero to very good, in under a
day ...
Most important of all, the subjectivity of spam ranking is catered for
when you have WebIDs and Linked Data in the mix.
One persons Spam is another's Ham :-)

Nathan,
SPAM busting is something Linked Data while handle very well. A
few moons ago when TimBL put out the GGG post [1], we had a little
experiment whereby you could only comment if you where at least
one degree of separation from an individual in his FOAF file. The
post has zillions of readers and not a single SPAM comment :-)
Sadly, the platform went down and the sole comment (mine) was lost :-(
The WebID protocol emergence marks the beginning of the end for
easy SPAM.
Make note of this re. WebID protocol usecases as we continue our
development of usecase collateral for the protocol :-)
