SimonTheBeetle: You've got a very interesting collection of friends, THAT I can tell you. LOL
They could almost be within the rules we have now, almost. The first activity mentioned on all the profiles is renting the L2 driver, "A" is the date that happened (probably the date the account was opened, but wgt hide that from us now). "B" is the date they last played.
Another thing is that although the avatars all look like something out of Cobra Kai (and I certainly don't mean the CC) there are two different ones marked # and ~. If there were two players there'd only be an issue on the 12th/13th. That said there are two distinct formulas to the names too and that would suggest 6,7 and 8 as on group and the others as the second, a fair bit of overlap there.
A B
6 ~ 04/07 07/07
7 # 06/07 09/07
8 # 10/07 13/07
9 ~ 08/07 11/07
10 # 12/07 22/07
I1 ~ 14/07 29/07
I think they've been banned anyway, probably not on apple device(s).
