I'm sorry to hear that and I'm really surprised that you got that before my welcome message? You don't still have a copy so that we can see when it arrived by any chance?
I manually approve all membership requests and send out the welcome message as I do so, this means there is a time lag of about 5 seconds usually!
In this case I had checked the ID but 'she' had cloned someone's (from Africa but quite legit) Linked in profile. If people are that determined to mess with stuff, a few are always going to succeed :(
A very good benchmark is the photo thing. You will notice that people missing profile photos generally get far fewer responses on SFN. This is partly because people like to see who they are chatting to and partly because almost everyone who has been a member for any length of time has met up with someone who has met up with someone, who has met up with someone - hence we 'know' and can vouch for each other. So if you get messages from people without photos it is a good warning sign!
We do also have a spam filter site wide on SFN which picks any messages like this up but obviously it can't work before the messages have been sent!
I can only apologise and reiterate again, please send James or I a PM if this happens otherwise we won't always pick up on stuff posted in threads like this. Thanks!
