Wikipedia talk:Sockpuppet investigations/123 editor

This user deleted my edit on the William G Gregory post. When i look closely to most of hes contributions on Wikipedia, i can se he is clearly vandalising pages which includes sites About Albanians, Bosnians, Croatians, Montenegrians etc, by ether removing or changing information, in many cases with a questionable purpose. What all theese countries have in common is the hostile relationships to the country Serbia, Which it also appears that that person may be an ethnic serb.
