order by username, result;

Items

Item history of all items touched by suspicious characters

SELECT * 
FROM itemlog, 
  (SELECT DISTINCT itemid 
   FROM itemlog
   WHERE source IN ('[charname1]', '[charname2]')
  ) As x
WHERE x.itemid=itemlog.itemid
ORDER BY itemlog.itemid, itemlog.id

Item history of all items touched by suspicious characters and someone else

SELECT * 
FROM itemlog, 
  (SELECT DISTINCT i1.itemid 
   FROM itemlog i1, itemlog i2
   WHERE i1.source IN ('[charname1]', '[charname2]')
   AND i1.itemid=i2.itemid
   AND i2.source NOT IN ('null', '[charname1]', '[charname2]')
  ) As x
WHERE x.itemid=itemlog.itemid
ORDER BY itemlog.itemid, itemlog.id

The string 'null' is required in the NOT IN clause because of register events

Bots

Finding Bots

TODO: {{{1}}}

Checking if someone is a bot

The following queries lists the number of "use"-actions per player and hour. If there are high number of uses for several hours in a row, it is likely a bot.

SELECT source, left(timedate, 13) As day, count(*) As cnt
FROM gameEvents
WHERE (source='[character1]' OR source='[character2]') AND event='use' GROUP BY source, event, day ORDER BY day;
