So I'm glad AI are being much more interactive Diplomacy-wise, that's lovely... but my Riftborn neighbors have asked me for an alliance literally every turn for the last 15 turns. Which I cannot afford as I'm currently already in a war and accepting that Alliance would stick me in another one. Can I get some manner of delay on AI propositions? Like, if you refuse a diplomatic offer, they won't approach you with another one for 10 turns or so?

Also, side note, but how come the AI always blames you for everything even when they decide to do something? "How dare you break our Peace!?" You're the ones who declared War on me! That was literally the last diplomatic you sent!

One thing that definitely has to be addressed is the amount of messages you get from the AI. I had this alliance request problem too in a few games lately, often several AI doing it, you can imagine the number of junk mail I had to go through every turn.

You monster! You left them alone in dark space without any hope!

P.S. Yeah, we really need instruments to avoid AI offers

That and AI complaining we are offering them no support... Yeah, i wish i could send help, but it's on the other side of the galaxy and I have no fleet nearby.

Would be nice if we could give them an immediate answer on such a request for help. If you accept, they expect your support within a number of turns, but if you refuse, they won't ask anylonger for a set amount of turns (their stance towards you should change accordingly).
