I'm not quite clear as to what you're asking in the above (or in the rest of your post), as your English is too difficult for me to understand this early in the morning, but I'd say no--what you described about members coming back to life and either asking to have feedback removed and/or joining bounties again isn't unusual at all.  I've had members I'd tagged 3 years ago go inactive and then, magically once bitcoin is booming and there's another altcoin craze (NFTs, DeFi, whatever), they've rediscovered the forum as a cash cow that they're going to use to milk dry yet again.

The general rule I've found is that once someone has figured out that money can be made here by bounty hunting, they never really go away unless they get banned and don't create a new account and fly under the radar.  A lot of members are from countries where the money they can make on bitcointalk and the projects that advertise here is far more than they could make doing hard manual labor for 12 hours a day, so who in their right mind would choose the latter?
