It sounds to me that you are taking your experience, disregarding other's experiences and views on it, and only comparing it to the negativity you have experienced. Disco's comment is not a 'thumbs down', it is how they feel and their take on your thread and the conversation that this thread encompasses.
I am sorry if you had a hard time with the shell you were in, or you were trying to get into... but not everyone has bad experiences. Applications to get into shells are not always a bad thing, it doesn't mean people look at it as a job and it doesn't mean the moment they get in people are going to ask 'what does your gf/wife look like' in every single shell.
My shell, as Holy has started, has an application and it is simply to make sure all members have access to the forum, see who is interested, how they heard of us (because this also helps us see how people are hearing about us), if they like the way our shell sounds based off our Creed, and then asks about bacon, pancakes and waffles. Om nom nom nom!
I for one agree with Disco's outlook on applications.
We do A LOT of planning, discussions, help threads and fun event sign ups (Woot Drunk Fishing!!!) on our site. If we just let people in and didn't have them sign up/apply to the site first then many people might not, sign up, get that information, or not know it is there. By making them apply to the site (which to sign up to the site at all you are required to fill out an app) we know everyone in the shell knows it's there, what we have to offer and has access to all information.
If they decide not to go to the site after that, then that is on them because we have given them all the tools they need for the shell. Yes there can be the extremes when it comes to shells and applications, but I don't think I have ever seen one that is extreme... and honestly if I saw one that was that bad it probably wouldn't be the shell for me anyway.
I don't know both sides of the story and what exactly happened to you to make you so negative (because you do seem overly negative...) against this, and I am sorry you feel this way. But just because it happens there, doesn't mean everyone is this way. Hope you have better luck with another shell or whatever you decide to do.
