Can you provide an evidence of that user was using above address? Because I didn't found it when using forum search. As other 4 users already tagged and provide full details by @YOSHIE.
You have to check the connection through its spreadsheet. I also thought the same as you at the first, if we search it through forum post then Mihab56 account and the address above didn't connect at all. But in campaign sheet showing that Mihab56 use the same address and facebook profile as Nadiya AktherMihab56 PoA link - https://bitcointalk.org/index.php?topic=5340981.msg57201631#msg57201631
