Seems weird. I've played this game for 10 years and i know the rules however....
You can get banned for sending 5 metal and 3 deuterium toa rank 1 player and it is considered pushing. [[((on a side note, receieving 'threats' from high ranking players because you meant to fleet save to an inactive planet, but hit theres instead, didn't fleet recall because a disconnect issue because of the bandwidth being used, seems absurd. Having actually recieved several of these it gets really weird being banned by a rank 40 player in a large universe because i sent resources to the wrong planet, messaged the guy and asked to get them back.]]))
Seems really really weird to get a ban for that, but i'll explain and give an example of a recent ban i got if anyone wants more info, go ahead and post.
Also, feel free to ad advice on what should be improved with the pushing rule.
Personally, on a side note, it seems like it's ridiculous to even trade with people because of how many times you end up doing a full fleet recall because someone did not send resources, or they are delivered, they believe it is a different amount than what they wanted etc etc. That seems to be a general concern.
Feel free to add your own opinions on other antiquated rules as well.
