Astroturfing Reviews in the App Store

[rainmanjam]

Has anyone seen this before to their own/other apps and is there anything that can be done about it?

looks like the other one is the better app

Maybe NJection needs to make a better app? I for one like other suggestions in reviews. There's SO much garbage in the app store, things like this sometimes help. If NJection had the better app, it would be reversed, and I guarantee no one from NJection would be belly aching.

I fail to see the problem. Make a better app, problem solved.
I feel that if you purchased an app, you should be allowed to say whatever you want about it, as long as it isn't offensive language.

I don't want to see heavy handed censorship coming from Apple.
