I have been a long-standing and prolific contributor to IMDB of trivia information, dates and mini bios. For years now, the same 'anonymous' individual has been tagging/hijacking my biographical submissions (and those of numerous other contributors) by virtue of adding/deleting a comma or inserting consecutive hyphens instead of commas. Often I find newly introduced grammatical or spelling errors which necessitate rewrites. This bottom feeder likes to claim the work of others in the way a cat sprays to mark territory. I am sure that there must be other contributors who feel as annoyed as I am. Is there no way IMDB can protect genuine contributors from this individual who even lacks the intestinal fortitude to put his/her own name ?
