I am not being hard here mate,but i guess i know why YAhoo never accept you as campaign participants for the reason of All your post are made in Russian Local board,things that will be harder for you to make through every campaign here in service section because what the manager needs are english posters though i know yahoo is accepting some local post but not to the extent that all of those will be made in such,i hope you get my point here and will take it as a concern for your further journey in signature campaign participating

Goodluck mate!!!
