What exactly would that entail? Would I only need to change my name when using admin powers or whenever I join the server, even as a regular player?
Sorry for the slow reply (busy weekend)
This is a tricky topic because it's mostly about PR - what qualifies as "good for the image of the community" and "bad for the image" is highly subjective and difficult to define clearly.
As others pointed out, having an admin named "Adolf Hitler" is most probably bad PR and we're going to get flak because of that - regardless of whether people understand the satire nature of the whole act.
The issue is that even if you were to leave the server and join under another name to carry out admin matters, people are going to notice - whether by behaviour (you leave, someone joins back, someone gets kicked, the guy that joined left and you rejoin) or by looking up SteamIDs.
Now in my opinion, that itself is not an issue; just like you can wear whatever you want outside of work, you can behave however you want (within server rules) outside of your "admin work". Personally I would not have an issue if you'd carry out all admin-related things under another name - whether on the server or in the forums. I believe that would be highly inconvenient for you unfortunately, but if you're willing to do that, I'd see nothing in the way of my +1.
