Edit: I've heard from other CLAM users that yobit is just as trashy as poloniex when it comes to deposits / withdrawals. What's up with these exchanges being incompetent with blockchain tech?
currently the CLAM wallet on yobit still maintenance and we don't know how long they will fix this problem.
is freebitcoins.com exchange has an API? if you had it, we can request into CMC to list the exchange to their website
