Yes, now it really has become much more difficult for bounty hunters to interact with bounty companies. I also have experience of such extension and my bounty company lasts for more than 30 weeks and each time is extended for 2-3 weeks. I can not get out of it, because I do not count all these weeks worked. So my choice is to wait and do everything as described in the company's terms or else all my work will be meaningless.
Please accept my condolences.Also I am a member of the bounty company Zero Carbon (social network). Already and throw a pity, got used to it)) But seriously that such projects are becoming more and more. It's all very depressing.
