You misunderstand me if you thought I was blaming Magnus for this. It was a hypothesis that right now seems false and we do not yet have another answer. I do think it is entirely possible that a high-volume, low-user-expertise game interface could generate problems very much like what we are observing. I think we should be able to track them more transparently than we can now.

The widar tag seems a starting point:

https://www.wikidata.org/w/index.php?title=Special:RecentChanges&tagfilter=OAuth+CID%3A+93

but this could be improved.

p.s. Side note on the game. Other very similar things usually incorporate some level of redundancy - e.g. you show the same thing to multiple people and only keep statements where 2 or more people agree.. Lower recall but higher precision - depends on the goal.

If I understand correctly:

1) Magnus' game already tags the edits with 'Widar'.

2) Magnus' game cannot merge protein and genes if they link to each other. With 'ortholog' and 'expressed by' Magnus' merging game does not contribute to the problematic merges (Magnus email from previously today: "FWIW, checked again. Neither game can merge two items that link to each other. So, if the protein is "expressed by" the gene, that pair will not even be suggested.").

There is nothing more that Magnus can do, - except making an unmerging game. :-)

In another thread, we are discussing the preponderance of problematic
merges of gene/protein items. One of the hypotheses raised to explain
the volume and nature of these merges (which are often by fairly
inexperienced editors and/or people that seem to only do merges) was
that they were coming from the wikidata game. It seems to me that
anything like the wikidata game that has the potential to generate a
very large volume of edits - especially from new editors - ought to tag
its contributions so that they can easily be tracked by the system. It
should be easy to answer the question of whether an edit came from that
game (or any of what I hope to be many of its descendants). This will
make it possible to debug what could potentially be large swathes of
problems and to make it straightforward to 'reward' game/other
developers with information about the volume of the edits that they have
enabled directly from the system (as opposed to their own tracking data).

Please don't misunderstand me. I am a big fan of the wikidata game and
actually am pushing for our group to make a bio-specific version of it
that will build on that code. I see a great potential here - but
because of the potential scale of edits this could quickly generate, we
(the whole wikidata community) need ways to keep an eye on what is going
on.
