They will. But they get warned and banned if they persist as it's against the rules to post alt coin threads in boards that don't have an alt coin section.
Is it allowed to post altcoin threads in local board which has altcoin section?
Conclusion: -As reported altcoin threads haven't been moved to altcoin section, it is allowed to post altcoin threads in local board and there is no need for new child board.
-As only posts in altcoin section are ICO announcement translations which no one reads, there is no need for altcoin section.
-Altcoin section should be trashed and every altcoin thread in local board should be trashed as well, but as long as altcoin section exists, altcoin threads are allowed in local board
-moderator is not needed in Croatian local because moderator will waste his time moderating Croatian local
