Facebook Apps: Anyone can give clarification?

[Arnie]

I have some questions about an App on Facebook.

After contacting Facebook about this App, Facebook stopped communication and their used email stopped existing quite soon after. I tried to contact the App admin on Facebook directly too and this particular App “My top Stalker” didn’t respond at all.

I try it this way now and hopefully someone can give me clarification:

It’s a questions about the App: “My top stalker” after a post on my Facebook-Wall saying it was posted by a person, saying: “<name> has posted on your wall”

I would like to know:

1. If the person put or send this app-message directly on my wall manually by himself (in person) or if it was randomly post by the "Application-Program".

The message was removed later on:

2. Who can have removed this message?
- The person who put this message there in the first place or the application itself?
(I didn't remove it myself).

Notes:
* I don't have ANY applications active or installed on my own page. I also NEVER get these kind of messages on my wall besides this time.
* I received the email message from Facebook that this particular person posted this on my wall.

Thank you in advance!
