The account was last active yesterday, have you tried to PM directly from the forum?
In fact, this is a common problem experienced by bounty participants when participating in unclear projects and BM with low rank. I don't mean to accuse, but I think BM has an attachment to the project where the project only uses forums and participants to get free marketing. I can't give you anything at this time other than the advice to only follow BMs who have credibility like @julerz12 and @irfan_pak10.
You are correct; the account, after being inactive since November 10, 2023, was active again on November 23, 2023. Several colleagues have contacted PM via this forum, but there has been no response at all from BM.
I'm interested in taking part in the bounty again because I took part in the first bounty and no problems occurred; BM paid on time. It was my mistake to just believe that, but because this has happened, I can only accept this situation.
That's right, there's nothing you can do anymore if BM isn't cooperative, he can't even provide follow-up on the current situation. Like the advice I gave previously, from now on only follow BMs that have a high reputation and credibility so that you will not experience an incident like this again.
Slightly correct the responses you make, you don't have to reply to them one by one separately, it would be better if you put them in one response, because otherwise the responses you make will be spam.
