WEADER25 AND NABBER [no form]

I am pretty sure that they are using multiple accouts. Both got new accounts and are from the same country. When i asked if they knew each other they said they didn't....but weader has only played games that nabber has been in. Neither one of them attack each other. They take their moves EXACTLY right after one another or always together......but they are never attacking or fortifying at the same time it's like he hit "take turn" one both accounts and let's one sit while he takes the turns for one...and when he's done he got right to the other. Is someone gonna do something about this?
