I don't know the Czech language well, so I will write in English to avoid mistakes. I am a member of the CZ community, like you. My nationality shouldn't matter.
I played in France, Germany, international servers, Italy, Portugal and other countries, I have played with players of other nationalities both in Italy and in other countries.
I don't open my alliance to Czech players because our forum is completely in Italian and full of slang, but I have no problem coordinating with other alliances and I enjoy playing grepolis with players of all nationalities.
Do I play at night too? Other players from other alliances do this too.
Do I buy gold? Other players from other alliances do it too
Does Innogames allow this? Yes.
Does the bonus benefit the defense and does the attacker lose more units? Yes.
Do we attack for no reason just to get push notifications triggered and disrupted? No.
Have we been at war with some alliances? Yes.
Have we made more conquests than other alliances? Yes.
@Thasoss,
these are innogames rules reported in czech language, right?
It's expressly written that attacking at night is allowed, isn't it?
