Is it a Facebook executive manager a person that creates a site that blocks people from adding friends on FB?

[Khoi Minh Vu]

When I was blocked from sending friend requests and messaging people who are not in my friend's list for 30 days, I didn't mean to send friend requests or send silly messages to any people I don't know, the Facebook team members said that they want to end the block immediately but they can't because they need to protect their policy and they said it was not their decision for ending the block or creating that site that keeps track of users on fb, so maybe because it is an executive manager's decision to create that site. But is it surely that manager who creates that site which tracks people from adding friends or blocks people?
