You could limit the number of bots in spec to 1 or something for that functionality. The issue is (as that screenshot shows) that server owners are placing x amount of bots in spectator to mislead players browsing the server list that are looking for highly populated servers. This is certainly not what we had in mind while dedicating thousands of hours developing omnibot .... However, I don't think the preventing bots from being in spec is the right solution since there are other ways to fake the number of players on a server. In my opinion, the best way to handle this would be to add 'blacklist' functionality to the server browser which would allow users to filter out servers they are not interested in.
