Your description is very vague but if you have a substantial source that goes into detail about whatever phenomenon it is you're describing then it might make a good submission on its own.

It's not worth a full post but one example of where Wikipedia still works is to find the current link for The Pirate Bay which often changes. One example where the link is being censored on Wikipedia is Kiwi Farms

thepiratebay.org has always been the domain, it never changed (expect for a brief period where they lost control of it due to internal infighting). You're probably thinking of something else.
