Recently wake up account for the sole purpose of joining bounty campaign should be reset merit.
That doesn't seem fair. Users have the right to participate in the forum any way they want as long as they abide by the rules. If users want to spend, or even better, waste their time on bounties, it's their right to do so. And they shouldn't have to face consequences for being bounty participants other than being ignored if they are spammers or banned if they are rule breakers, ban evaders, etc.
I have a friend with legendary account here that already inactive for a long time. He is the one who mentor me on Bitcoin and introduce me this forum. He contribute some knowledge and spend time here during he is active.
So if your friend one day decides to return and takes part in bounty campaigns, he should have his airdropped merits removed? Or do we let him keep his merits due to his past forum contributions? There is no way to make that work without causing controversy, and we don't need more of that. Users should be motivated to join the forum, not be sent away.
