For those who are curious about national flags and maps . . .
The answer is that it has nothing to do with flags at all, it's just another attempt at an internet scam. The bit about the flags was just filler text. The person who posted it was just looking for something to post so that they could get their link out there at the bottom of the post and hope that someone would click on it.
Be wary of clicking on any link in someones signature or post. That's not to say all are bad. Most all of the links here are safe, and there are some members who have links in their signatures that I wouldn't worry about clicking on. Just use a bit of common sense. If the member is new, only posted a few times, or the posts don't seem meaningful or relevant, then that should be a warning to proceed cautiously.
Over the past month we have had several new "members" who have joined apparently for the sole purpose of promoting other sites. One was for a country club in Canada, one for a textbook reseller, and one for an educational supply company. Probably all legit businesses (perhaps), but very inappropriate way to advertise. In this particular case, all the sham members were from Pakistan. In the past we have also had "members" who were promoting sports drinks, multi-level marketing gimmicks, and electronics.
So stay alert, and be safe!
