Appeal prosess being 'selective'?

I've been watching all this time and began to think that appeal process in this forum is much 'selective'. Newer appeals have been processed — and got their result — more quickly while some older appeals, including mine, still no answer.
Any thoughts?

I guess it depends on the evidences every one have on their appeals. There are many of them easily to answer. And some of them not... For sure as much more info you give it doesn't means that it is easily to process it.
