A few days ago I've noticed a huge spike in downloads on one of my apps (that I haven't touched for about two years). This app averages 10 daily downloads. This spike brought 7k downloads D1 and almost the same D2, altogether around 14k downloads. When I investigated I saw that all downloads came from a search feature and from iPhone only. Even tho I'm accustomed to spike downloads this one was really strange - the conversion rate on the app store was around 80-90% which is highly unlikely (at least only from search). Additionally, I didn't have a single impression on my ads (in such spikes this would mean in thousands) or a single rate from that country. I came to the conclusion that these spike downloads are most probably bots, but I'm not 100% sure since this is my first time dealing with such behaviour. Now I've got the message from Apple "We are writing to inform you that your company is not in compliance with the Apple Developer Program License Agreement (PLA) Section 11.2. Please investigate and promptly address issue(s) related to manipulation of App Store chart rankings, user reviews or search index." First I thought that this was a spam E-mail but the domain matches the real one and since I've really got issues regarding the spike of downloads, I almost don't doubt that this is a real E-mail. I plan to write Apple about this from what I've know, but I'd like to know if anyone experienced something like this? Even tho the downloads from Japan are not reported on this app anymore I've removed it from that particular App Store. What can I do if this happens again? Any advice on this issue would be much appreciated. Thank you :)

I have a game that unlocks some levels later in the game where the user reaches a certain point. There is no shop button or something similar. However, this means that the Apple Review probably won't "see" the IAP. Is this okay with App Store guidelines or does need to be some sort of "shop" where you can (also) purchase the IAP from there? Thank you :)
