" User accounts and IP addresses may be blocked from editing to protect Wikipedia from disruption."
“A report in Huffington Post recently revealed the case of Wikipedia editor Ed Sussman, who was paid by media clients such as NBC and Axios to help diminish critical material. Paid editors operating in a similar manner to Sussman have worked on behalf of CNN contributor Hilary Rosen and the CEOs of Reddit and Intel, among other clients.”
“The editors who can work harmoniously in pursuit of this ideal goal of neutral “consensus” can make editing Wikipedia a wonderful and productive experience. Yet in other cases, it can result in ongoing ‘edit wars’ in which groups of headstrong editors group into dueling factions that duke it out for supremacy of their version of the page—“consensus” achieved not through impartiality but through the greater endurance of one side of partisans…administrators and longtime editors have developed a fortress mentality in which they see new editors as dangerous intruders who will wreck their beautiful encyclopedia, and thus antagonize and even persecute them. This attitude comes from the fact that some of these intruders are indeed trolls, partisans, paid hacks, or incompetents… Wikipedians’ general indifference or even hostility to outside opinion.”
