I tried to search for Friendster in the App Store and didn’t see it among the first few results. Instead, App Store was returning a sponsored ad followed by normal results for all other kinds of similar annd less similar apps. Instagram, Snapchat, Yubo (never heard of), Monopoly Go (mobile game related to the board game Monopoly), BeFriend (never heard of), Tinder, Friendly Social Browser (never heard of), Facebook, and at that point I stopped scrolling the results.
For a moment I thought maybe the app was US exclusive or something and not available in my region.
But following the link from the post worked fine and I could install it.
I literally searched Friendster and the app is named Friendster but App Store gave me all kinds of other crap in the search result instead. Weird.
Anyway, installed the app finally thanks to the link.
Odd, Friendster was the first non-sponsored result for me in the U.S. store.
When a new app is released, it takes a few days for it to get into search, for some reason. Pretty much every single time a new app releases I see a comment like this. Nothing malicious you just have to wait a bit.
