Well,
Apart from the fact that they're both using ttttttttNNNN type of usernames, they are also collecting negative feedbacks and cancelled transactions:
https://www.lddb.com/feedbacks.php?user=jaydenborn2020 (-6, 10 cancelled out of 30)
https://www.lddb.com/feedbacks.php?user=mikey1992 (-4, 14 cancelled out of 29)
Is there a pandemic of CARARTE-19 going on?
I contacted mikey1992 about this, he never replied.
I just contacted jaydenborn2020 as well.
