This account belongs to an established wikipedian who wants to give compliments anonymously. Said wikipedian does not believe this violates sockpuppet policies, but if it gets blocked c'est la vie.
Explanation edit
If I give you these pretty barn stars from my main account, you may (if you have seen me edit) like em less (or more) cause they're from me.
If you get em from this account... well all you know is someone appreciates it, and they could have no motive other than to say so.
