But it doesn't appear to be a type 2 or type 3 flag [AKA the "scammer flag"], so it'll remain as a yellow banner.
Thanks for the explanation, I'm not too familiar with the differences in the flag, it's a pity that the OP did not choose the option that will show a red warning - although I think that does not prevent anyone from creating such a flag. Unfortunately, as things stand, I don't think the OP will be the last victim of this scammer.
