I do get your point and ive been a victim of these spammers and multis etc but its better you get used to it and stop crying as its been going on in bd for years people learn to live with it.
It seems you guys are just upset about e3, but to be honest i didn't see any spammers plant and spam, if anyone did plant they planted and joined a team and played. The so called spammers you are referring to were teams that attacked you due to your lack of diplo because you thought you had already won once you made those players leave the team you were fighting.
As muha rightly said some people plant late on and win. If someone plants a new colony and spams, just report it and admin will ban and sometimes compensate you if the damage was big. The end of the day its a war game. Be prepared for anything and everything to happen.
