Adding gas to the fire, Joe and Anna liked Emily's last post, Joe and Mike liked the second last and Joe liked the third.
All posts were up by january-may of this year, if they were recording something I think the timeline lines up.
The other two older posts, has no likes from them..
And a thing that I thought it was suspicious is that Mike doesn't follow her at the moment, and liked the second post.
Maybe he unfollowed her to avoid what we are doing right now? hehe
but yeah, it maybe all coincidences, we'll see
