it seems you haven't been following the news recently. Some fake tourists (or eternal tourists) have been turned down as soon as on their second entry.
no, the previous comment is right and it explains well why. Immigration can refuse entry if you have a story of abuses. The visa is issued by the MOFA, which can't enforce migratory laws from abroad. Once at the airport or land border, it's up to Immigration to let you in or not. 99,9% won't have a problem, but it's not like they have the obligation to let you in.
yes, they ask for entry and exit flights, it doesn't need to be to the same country, but the problem is the OP doesn't seem to have an exit flight. He should have submitted the information of both the entry and exit flights when lodging the application.
If they ask for something, and you flatly ignore it, they will just reject your application. You must submit whatever they ask, and you've got up to 14 days to procure the things, each time they ask for additional documents.
if you go to another country to explore, or because you want to go there, etc., it's not a "border bounce", as normally that expression is used when you go in and out just for visa/migratory reasons.
