We have deleted testing users from db. As you suggested, there are better ways to test the system and we have created a new workspace. Now all bets are made by human users and your gaming experience is not modified in any way. We probably made a mistake thinking it wouldn't affect gaming experience, and we are sorry for this. We have insert test users as a standard programming procedure and we would like to point out that we did it in good faith: we have first of all, admitted the existence of test users, and now we have worked several days on code and db to clear up any doubts. So we are sorry for mistake, and we are proud to communicate that the problem is solved.

Thank you for compliments, Chrille55.
