two Accounts one person's :
Cars with the same color, the same car brand, it cannot be ascertained that the car belongs to one person or the same person.
So, to prove that the car belongs to one person you must have valid data for both cars, otherwise you will be accused of fabricating false information about both cars, you know what I mean.
What i said above is an example, even though you see @BitcoinGirl.Club & @magneto, coincidentally did the last post on 15th may, not that they are as you suspect, if you check multiple accounts in this forum stop posting the same date, like: @...@..@.., are they Alt, of course not, if not validated and signed in sense.
