is it possible to remove the game lock?

I have never broken the rules or used cheats, but this morning comes the notice of an indefinite lock. the reason is "exploitation of bugs and errors with the goal of achieving an advantage in the game", but even now I do not understand how this can be used in principle. ._. in general, the ban came just like that. I heard that it seems like you can appeal it by writing to the developers, but after an hour and a half of searching, I did not find how to contact them, therefore, I hope that at least here you can help, yes ... well, or will tell me how you can contact them. : ")

( I apologize in advance for mistakes, the translator can be blunt )
