After checking up on this, we found that Bobby agreed (with Amy) to approach the neighbors and confront them.
According to Bobby the neighbors completely denied knowing anything about a man ever approaching their house AND did not confess to leaving that door-cam message. Bobby told us that he got a feeling they were lying. The inconspicuous man never returned. They asked us to take the video down from Hollywood Hamilton's IG, so we did.
Bobby has also agreed on "putting a little bit more attention into their marriage", and have stayed together. Things are going fine. We sent a them both a dozen roses and Amy told us she's decided NOT shove them up Bobby's ass.
