The query http://en.wikipedia.org/w/api.php?action=query&list=blocks&bkusers=Trollymomo produces the following output:
<block id="1216890" user="Trollymomo" by="J.delanoy" timestamp="2008-11-16T02:22:22Z" expiry="infinity" reason="abuse of talk page" nocreate="" autoblock="" />
If we were to look up this user in [[Special:Ipblocklist]] (http://en.wikipedia.org/w/index.php?title=Special%3AIPBlockList&ip=Trollymomo) we would get:
- 11:22, 16 November 2008, J.delanoy (Talk | contribs) blocked Trollymomo (Talk | contribs) (no expiry set, account creation blocked, cannot edit own talk page) (abuse of talk page)
The API query neglects to mention that the user cannot edit it's own talk page.
