Name Change/ Alter

I have been outed by a few people at my work place. They search my post history to see how much I post which can get back to my boss. I asked very politely for a name change.
The admins ignored it.
I signed up for a new name altogether (worried more about job safety than a post count) and now you guys have immediately suspended posting priveledges on that one.

I hate to sound like that customer who is going to 'take his business elsewhere' but I really need something to change.
