Apple banned him so he went underground. He used to go by Khalid Shaikh on the Android Market, but lately his apps have been showing up under the alias Sapphire Apps. His company name Perfect Acumen can still be seen in his package names and the annoying flood of his “Top Sexy Ladies <insert female celeb name here>” apps (which most users seem to view as spam) keep him from being hard to find. He packages a few pictures he finds on various websites into a slideshow and attempts to sell them for $5 each. The vast majority of his apps have a 1 star rating, and mostly because that is the least you can rate an app.

Khalid Shaikh Spamming the market with low rated apps
He currently has 178 apps listed on cyrket.com and was up to over 900 when Apple banned him from the AppStore. Google, it is time to stop Market spam and give us a filter option!
*Edit* While I was writing this (and after counting) Sapphire Apps posted 2 more apps to the Android Market. This puts his count up to 180.
*Edit2* 3 more apps were posted within an hour of this post. Grand total 183 and counting. At this rate, he might hit 300 before noon tomorrow.
