Ok...

The top picture is a screencap from the talk page of user Pellyeve93 of a comment posted.

That mentions my username.

And from the timestamp, seems to be from 29/05/2013.

Despite the fact that I didn't join the Wiki until 01/08/2013 as shown in the bottom screenshot. Am I misreading the timestamp? Or... what?!
