>>72485400I just fucking remembered this one too.
The image itself is fake since she never actually made this her username, but the date matches up perfectly with the statement that she first started talking about graduation on the 26th.
My rrat is that this was her self reporting, knowing that we were watching her name changes anyways.
The only other date that would make sense is between jan 1 and jan 11, as that's when she first started changing her names, and that's also when she started unprivating a bunch of old vods.
