This is a fairly common problem for all bounty hunters, especially now that Ethereum, which is often used for bounty campaigns, still faces difficulties with high transaction fees and many projects are migrating from one platform to another.
However, even in the telegrams of each project, it is rather difficult to find the necessary information and keep track of important changes in the project, since even in one day hundreds of new messages sometimes appear there.
It seems to me that it would be reasonable and logical for the bounty manager to publish in the first messages on the first page of the bounty thread about all important announcements for bounty hunters. We should not lose the earned tokens just because project teams often change the terms of agreements.
