One can only go by experience. I received a cold call today from a firm purporting to be L J Properties. I always hang up on cold calls anyway, but in this case, I also searched and found this site and looked up the number. I found a mine of information on these scammers, listed under both their mobile and landline numbers. Of course there will be red herrings or whatever, even the sites themselves posting counter-information, as was the case with this one, but credit where credit's due.
