For example, in Brawls there are multipliers and additions like extra mana or +/1 speeds that the guilds get through building levels. Could this logic apply to bots too?

In the brawl I played 2-3 weeks ago, the guild that ranked first was called XBOT.
There are bots that are very efficient and also play in brawls and probably burn cards to receive DEC...
I too am curious to see what the anti-bots measures will be like but I think they will be measures that will prevent bots from entering the game like in other games so a bots will not be able to start a battle.
As there are efficient bots so there are many efficient solutions already used by many web 2.0 and web 3.0 games.

For example in a web 2.0 game my daughter plays there are bots but they are game company bots that only come into play when there are few players.
In my opinion there should be the same situation on Splinterlands:

• Only real players
• only Splinterlands bots that enter the game when there are few active real players and receive no rewards
