It was brought to my attention that somebody is using my handle to post on some providers' websites. I'm not sure what the point of this is but it needs to stop. It doesn't really cause me any grief, but it does lead to some unnecessary confusion. Leave it alone.
I can see where that could be a problem but, unless he claims to be DP from ECCIE, it's very possible that the guy has never heard ECCIE and just liked the name. If this post doesn't dissuade him you may need to post on the websites where he's using the handle.
