The ICO has finished already two months ago but it seems the bounties have not been paid yet... am I right?
Yes, it is correct. Developers remember about that, they are in the process or reviewing. I'm not sure why do we have such a delay but maybe there are some legal nuances they're working on.
They should probably try to keep an open channel of communication with the people who have advertised them before bad rumors start to spread about them.
