You wish for your contribution history to be deleted? I'm not sure exactly what you think we can do about your contributions here. If you were actually wondering where they all came from, at least 59 of them are edits to your user page and talk page
Re: Re: Your Request
No it's not possible to just delete all your contributions like they never happened. I could try to look more into that to see if there's a way I don't know about if you had a pretty good reason to want them gone.
