In cases with an identifiable author, who is contact-able by wikidot, or once was (which is almost every author), then nothing should be added to their articles without their permission.
There is another facet, though.
If a method of tale crosslinking was standardized, and framed properly, then staff would have the option to add these crosslinks to old articles for which the author is unknown.
This is a big if, but if this situation arose, I suggest that this be allowed.
Why?
Because this would not damage the integrity of older articles. They were not created under the paradigm of "author creates a single, permanently static document". People modified them left and right, by default. Far as I know, the vast majority of the older articles have been altered by many writers, to create the versions currently standing on the wiki.
This is no longer the case, partially as a reaction to overreach by people like Fish who dramatically over-edited, and partly because things got too big to allow for that.
However, technically we have harmed old articles' integrity by no longer allowing them to reflect their original intent: to change.
This isn't how things are now, or even close, (people are uncomfortable even with open test logs!) but maybe it won't stay that way forever.
Either way, something we — and I — have worked years to re-establish: maintaining the integrity of SCP articles does not equal ensuring that they never change.
However, it really would need to follow an established standard. A simple addition of a single link (as in this case) is inappropriate.
