Or even better,
Check the stats on their own database (i.e. the App Store).
I found this just now: http://www.iappphone.com/stats/
The top 5 "Submitters"
Brighthouse Labs - 1855
Iceberg Reader - 1369
Molinker Inc. - 1011
FidesReef - 825
iLike inc - 588
From 15 minutes of research, its pretty clear to see that Brighthouse Labs, Molinker and FidesReef were (/are) definitely polluting the App Store.
In some cases, its very clear why Apple have introduced the "In App Purchasing" - most of these should probably disappear when all the duplicated Apps get merged back to a common one.
But from Apples point of view, they're still trying to prove that their platform has the most Apps. They've already put the "technology" into place - so now all they need to do is rush in and save the day, by forcing the developers to merge their Apps.
But seriously, with power comes responsibility. They're finding out that its not always easy to walk that tightrope.
