I fear my games may contribute to both problems (merging two items, and adding a sitelink to the wrong item). Both are facilitated by identical names/aliases, and sometimes it's hard to tell that a pair is meant to be different, especially if you don't know about the intricate structures of the respective knowledge domain.
An item-specific, but somewhat heavy-handed approach would be to prevent merging of any two items where at least one has P1889, no matter what it specifically points to. At least, give a warning that an item is "merge-protected", and require an additional override for the merge. If that is acceptable, it would be easy for me to filter all items with P1889, from the merge game at least. On Wed, Oct 28, 2015 at 8:50 PM Peter F.
