the purpose of the lobby server (imo) is to play games, its not to advertise downloads.
we had this discussion some time ago, i'm not sure if there was some conclusion.
if you think these game adverts are not ok, then our conclusion would be, that bot messages aren't allowed at all, imo we should apply this rule to #newbies.
if you want to advertise you should add springweblobby to http://springrts.com/wiki/GamesDownloads
for example. also i wonder why nobody requested to add springweblobby to the official installer.
(imo all lobbies should be removed from the spring installer at it should be sth. like a SDK, but thats a bit of work as download pages have to be adjusted)
sadly thats quiet a complex problem
