Information Age have written a very helpful article about the use of social networks for business, and the implications of this. Members may find the article interesting:

It does also remind us to be careful of the language we use, although the BizFace rules clearly say personal remarks must not be made, given the issues all websites have with some members I guess it is worth stating again.
Thankfully, the majority of our members are genuine, but the best way to be sure is to check feedback and ask people, before spending any money.
Hope you find the article useful.
kind regards
