Accuracy is preserved via peer pressure from the community of active contributors.
If it is the will of that community to distribute misinformation then that is what the wiki will present to the world. However, in practice it is typically the occasional rogue user who might attempt to contribute misinformation.
Every page edit is logged and the edit history is visible in a recent changes log.
Every user has the ability to undo a recent edit by another user.
Every wiki article has a companion talk page where discussion of erroneous or controversial edits should take place.
You may configure your personal preferences such that whenever you contribute to an article then that article get's added to your personal watchlist. You may then opt-in to be alerted via email of any subsequent edits to any article on your watch list. (I use either the weekly or daily "digest" version of this notice so as to cut down on email inbox clutter.)
If a particular user or anonymous IP address is seen to be vandalizing the wiki then there are ways to block that user (or IP address) for varying periods of time. Having said that, it has been my experience that this level of reaction is
rarely appropriate. A polite note at the offending contributor's talk page seeking clarification of the intention of their edit is usually enough to stem the tide.
In wiki culture the assumption of "good faith" is paramount.
Even the most juvenile vandal tends to respond positively to a respectful enquiry message. Very often, the wiki contributors/administrators who post stories/complaints about incessant vandalism are also the contributors who use inflammatory statements themselves or they are heavy handed administrators who tend to abuse the sysop privileges they have been granted.
So it tends to be case of "what goes around comes around".
In such a niche community as the Virtual Skipper community I doubt that there is sufficient motivation for a large scale misinformation campaign. If it should happen then the tools described above are available to nip it in the bud.
CAUTION: The VSK wiki has been given special permission to host
ZIP files. We all know that these are the expected form for boat models (maybe 40 or 50 of these) and skins (maybe hundreds of these) however this could be abused by an unscrupulous person to distribute malware. If you should discover such content in a ZIP file at the wiki then leave a message at the talk page for that ZIP file. You may also insert the special template {{delete}} at the ZIP file's information page. Either way it will be noticed and the offending file removed in fairly short order.
