There is a possibility that information might have been culled from this site for use by ill-intentioned persons.
This is not unique to us - I am afraid it happens all too frequently on the internet and most users will have seen examples of Spam and other varieties of nefarious use, so this is just a warning and reminder that all should remember to be on their guard at all times.
There are a couple of useful sites offering guidance.
''Fight Spam On The Net'' gives news and tips http://spam.abuse.net/
''Hoax Slayer'' categorises different types of hoaxes, phishing and other varieties of scam and offers a search tool to identify specific scams. http://www.hoax-slayer.com/
