Hi,
There are lots of cloakers on the market:
noipfraud, blackjack, trafficarmor, fraudbuster etc.
I'm just wondering if a particular cloaker should only be used for a certain traffic type(facebook/search/pops/display)?
Cheers 
Cloakers became a very small part of the whole game in my opinion.
I've heard of people recommending each of them - no overwhelming one recommended over the other. It's kind of a race to the bottom, cloaking works less often nowadays and it's also less important for everything you do. That's no edge anymore basically, simply from the fact that there are at least 4 equally recommended services out there for this.
I tried Blackjack (JCI) for a while and didn't like it much. Then switched to FB which had some weird problems with stats.
And now I heard good things about and was recommended Noip by at least 3 people saying FB doesn't work anymore.
So I really don't know what to think.
Pavel - keen to understand better what issues you are referring to. Rather then discuss here probably best to chat so ill PM you a link to follow up.
