Unfortunately I'm not a Michael Jackson expert, so I can't judge whether those edits were constructive or detrimental to the quality of the article. It appears to me more as a case of content dispute rather than vandalism, so you'd need to consult other editors of the same article, or Wikipedia:Mediation for help. If you suspect the same editor has been operating under different names, ask for help from Wikipedia:Sockpuppet investigations. I'm sorry I'm not in a position to help, and hope you find that useful. --Deryck C. 08:48, 13 May 2010 (UTC)
