I think something that is key to keep in mind with ANY unnamed source, etc., is that you have to take it for what's it worth. My thoughts? Take the tidbit of info, run with it, see what I can find that's verifiable, etc., then make an informed opinion about that validity of the information, or not, as the case may be...
..........
Sure, to come on here and say, for example, "well a source told me that John Doe used to be married and was arrested for spousal abuse." To post THAT, may not be correct. What SHOULD be posted, is the WebSleuther digging up of a link to the arrest warrant when Mr. Doe beat his wife....having done that BASED on the source's information. OR, perhaps if the WebSleuther has hit a brick wall, is it not ok THEN, to come on here and say, "listen guys, someone told me this info about Mr. Doe, and I need help VERIFYING it??"
Just my thoughts...
