what happened to this person on facebook?

[coward]

My ex gf recently got new boyfriend on her facebook and they were all over each other on their fb walls. But I supected this new boyfriend of her isn't real person but either hired or someone who doesn't live close to her and acting out fake relationship to make me jealous. I don't really care even if she goes out with other guy but the fact she fakes it makes me angry. I saw numerous sign of why this new bf was fake.

sign #1 - they weren't trying to hide anything and post all kind of love love stuff but there weren't a single photos taken together. If they were close enough to sleep together and make their relationship open on fb, obviously there were trying to make it public but no pics taken together? lol

sign #2 - girl talking about a single guy and how great he is and how much he loves her all the time all of sudden looks very suspicious.

sign #3 - every single posts they posts saying this sign "with xxxx" even though they aren't in same location together.

So I pretty much think this is some kind of fake stunt she's pulling off to piss me off. So after a week later, I asked my friend to write this new boyfriend of hers a message about those signs on his facebook wall and next day this guy was gone from facebook. He's unsearchable and all posts he posted on my ex-gf were gone. I know facebook setting allows to hide posts on your wall from viewed by others but they don't hide posts you posted on others wall too. So what happened? Did he get banned from facebook or maybe disabled his account coz he's got busted? I don't think there's setting to hide posts you posted on other's wall but only on your wall. His account was active since 2012 and had lots of friends but something seemed very off. If you are in a relationship and both sides are rubbing on each other all day long on each other's wall, isn't it natural they should have at least few photos taken together on their fb? well.. what do you think?
All his posts aren't visible on my ex's wall when my friend goes to her fb wall and it's not visible to me either. He's not searchable to me or my friend and when I made new facebook account and checked, he's still not there. I don't think there's setting to hide your posts that you posted on other's wall even if you set your privacy setting to only you. Also, if she wanted to hide him from me, she shouldn't have posted all her wall post public in the first place. I think her fake bf disabled his account.
