The strategy for updates, especially the correction or removal of misleading or false information, can be very complex, even for straightforward requests for updates of out-of-date information. First, we’ll assess whether there is adequate reliable sourcing to support the update. Then we’ll write the updates, with citations, on a document for your review for accuracy. The next step is submitting to an independent editor to review the proposal. The discussion page of the article, for those with an existing interest, is a standard starting place. The official Wikipedia queues for review of proposed edits by COI editors can be turned to in other cases . We also can help manage situations where multi-editor discussions and voting on proposals become necessary — often involving highly technical arguments over obscure Wikipedia policies. e.g. what constitutes a “Coatrack” (extraneous content) in a biography of a living person (“BLP”) In these situations, more experienced editors often can intimidate less experienced Wikipedia editors with technical jargon. Unless you have an experienced Wikipedia editor very familiar with Wikipedia policy working with you, your position might not be properly represented.
We’ve had great success with Wikipedia “crisis management” – getting highly misleading or false statements, that are very damaging to reputation of the subject (especially people), removed from Wikipedia. The more hostile and dedicated an “axe grinding” editor(s) is, the more work an assignment like this takes. It can be time consuming assignment, unfortunately, not to mention a highly stressful situation for the subject of an article being unfairly attacked on Wikipedia. Ultimately, with an apppeal or appeals, situations like this will be fairly resolved.
