Correct, in addition to add more work by Menapay after everything was ended I see this as blackmailing the users to leave a five-star-rating (the best one) for the app, otherwise they don't get their bounty tokens. That's similar to buy reputation for Menapay and has nothing to do with ratings left for a legitimate reason because the users are forced to do it and if they won't do it, they don't receive rewards for their work.
The word "blackmailing" is what i missed in the OP, this is exactly what this whole thing is about , if you read the chat between the bounty manager and the ICO team, the ICO team's excuse was that they wanted to verify the existence of the bounty hunters, assuming that many of them could have been bots or what he refers to as "dead people".
the funny thing is, downloading an app is an easy task for a bot, if they wanted to confirm the existence of the hunters there could have been better ways of doing this, but your theory makes sense, they want those "fake/forced/bought" 5 stars rating on their worthless piece of shit app.
