So I came back playing BD after few years, now here is the situation.

I got conquered by enemy alliance as I was leading a sub, using my diplomacy skills, I was able to make the enemy alliance to mark me at peace in exchange of helping them take down another alliance and I did a successful rebellion, now with my diplomacy skills again, I was able to sleep in peace, when I woke up, me and my (former) conqueror had been banned(farming?) for 12 hours, now both our reputation was worsened.

Now may I ask what farming is? I thought it was like:
1. Being conquered forever. (didn't happen because I rebelled)
2. Spamming OPs for the person. I only made 4 OPs (1 razed, 2 took away by another alliance not related to me/the other party at all, I still own the other 1*it's my TB/Barracks now*)

I came back after 4 yrs? and asking some of my friends to go back too, now I think I shouldn't have gone back, this will be my final era and will not go back for good now.
