The BOT Seer found on the metalforge .net server is working.
As a player, I use him occasionally.

This is what the client cmdline tell Seer help responds :

Seer tells you: 
I'm a bot, and I'm writing kill logs for all players and monsters.

You can ask me about:
 last <player>  to see when the player was here
 last           to see the last 10 logins/logouts

Seer tells you: 
 uptime         for the time the server's up (at least)
 tell <player> <something> to let me tell the player something when I see him
 maps           to see the most popular maps

Seer tells you: 
 kills <name>   to see what a player or monster has killed and how
 numkills <name>   to see how many times someone killed
 how killed <name> to see how someone prefers to kill

Seer tells you: 
 deaths <name>  to see who killed a player or monster and how
 numdeaths <name>  to see how many times someone died
 how died <name>   to see how someone prefers to die

Seer tells you: 
 what killed <name> to see what attack caused someone to die
 did <name> kill <name> to see if/how somebody killed somebody

 find <name>       to see all matching monsters or players

Seer tells you: 
Besides this, I'm afraid I'm not very intelligent. :)

Some years ago (Modification time tells me February 2013), I found a Perl script on the net, that contains the above lines.

#  - allow several admin users
#  - implement numdeaths, numkills
#  - 'forget <script>' and 'stop <script>' commands implemented

#  - added events_stats callbacks
#  - we now log the players that enter a map whose name matches a pattern in
#    the predefined array @check_maps
# 
# 2003-02-13 Release 0.9.7
# 
#  - 'last <player>' now also shows the host name
#  - implemented the 'host <player>' command which tells the player's hostname

I'm a bot, and I'm writing kill logs for all players and monsters.
 
You can ask me about:
 
 last <player>  to see when the player was here
 last           to see the last 10 logins/logouts
 uptime         for the time the server's up (at least)
 tell <player> <something> to let me tell the player something when I see him
 maps           to see the most popular maps
 
 kills <name>   to see what a player or monster has killed and how
 numkills <name>   to see how many times someone killed
 how killed <name> to see how someone prefers to kill
 
 deaths <name>  to see who killed a player or monster and how
 numdeaths <name>  to see how many times someone died
 who killed <name> to see who killed someone
 what killed <name> to see what attack caused someone to die
 
Besides this, I'm afraid I'm not very intelligent. :)

 running             shows all currently running scripts
 scripts             shows the names of all known scripts
 stop <scriptname>   stops a running script
 forget <scriptname> deletes a script
 
 stats               to see my character statistics
 add_admin <player>  to add a player to my admin list
 rem_admin <player>  to remove a player from my admin list
 admins              to see who is on my admin lists
